trait Importer extends AnyRef
This trait provides support for importers, a facility to migrate reflection artifacts between universes.
This trait provides support for importers, a facility to migrate reflection artifacts between universes. Note: this trait should typically be used only rarely.
Reflection artifacts, such as Symbols and Types, are contained in Universes. Typically all processing happens within a single Universe (e.g. a compile-time macro Universe or a runtime reflection Universe), but sometimes there is a need to migrate artifacts from one Universe to another. For example, runtime compilation works by importing runtime reflection trees into a runtime compiler universe, compiling the importees and exporting the result back.
Reflection artifacts are firmly grounded in their Universes, which is reflected by the fact that types of artifacts from different universes are not compatible. By using Importers, however, they be imported from one universe into another. For example, to import foo.bar.Baz from the source Universe to the target Universe, an importer will first check whether the entire owner chain exists in the target Universe. If it does, then nothing else will be done. Otherwise, the importer will recreate the entire owner chain and will import the corresponding type signatures into the target Universe.
Since importers match Symbol tables of the source and the target Universes using plain string names, it is programmer's responsibility to make sure that imports don't distort semantics, e.g., that foo.bar.Baz in the source Universe means the same that foo.bar.Baz does in the target Universe.
Example
Here's how one might implement a macro that performs compile-time evaluation of its argument by using a runtime compiler to compile and evaluate a tree that belongs to a compile-time compiler:
```
def staticEval[T](x: T) = macro staticEval[T]

def staticEval[T](c: scala.reflect.macros.blackbox.Context)(x: c.Expr[T]) = {
  // creates a runtime reflection universe to host runtime compilation
  import scala.reflect.runtime.{universe => ru}
  val mirror = ru.runtimeMirror(c.libraryClassLoader)
  import scala.tools.reflect.ToolBox
  val toolBox = mirror.mkToolBox()

  // runtime reflection universe and compile-time macro universe are different
  // therefore an importer is needed to bridge them
  // currently mkImporter requires a cast to correctly assign the path-dependent types
  val importer0 = ru.internal.mkImporter(c.universe)
  val importer = importer0.asInstanceOf[ru.internal.Importer { val from: c.universe.type }]

  // the created importer is used to turn a compiler tree into a runtime compiler tree
  // both compilers use the same classpath, so semantics remains intact
  val imported = importer.importTree(tree)

  // after the tree is imported, it can be evaluated as usual
  val tree = toolBox.untypecheck(imported.duplicate)
  val valueOfX = toolBox.eval(imported).asInstanceOf[T]
  ...
}
```

trait InternalApi extends AnyRef
Reflection API exhibits a tension inherent to experimental things: on the one hand we want it to grow into a beautiful and robust API, but on the other hand we have to deal with immaturity of underlying mechanisms by providing not very pretty solutions to enable important use cases.
Reflection API exhibits a tension inherent to experimental things: on the one hand we want it to grow into a beautiful and robust API, but on the other hand we have to deal with immaturity of underlying mechanisms by providing not very pretty solutions to enable important use cases.
In Scala 2.10, which was our first stab at reflection API, we didn't have a systematic approach to dealing with this tension, sometimes exposing too much of internals (e.g. Symbol.deSkolemize) and sometimes exposing too little (e.g. there's still no facility to change owners, to do typing transformations, etc). This resulted in certain confusion with some internal APIs living among public ones, scaring the newcomers, and some internal APIs only available via casting, which requires intimate knowledge of the compiler and breaks compatibility guarantees.
This led to creation of the internal API module for the reflection API, which provides advanced APIs necessary for macros that push boundaries of the state of the art, clearly demarcating them from the more or less straightforward rest and providing compatibility guarantees on par with the rest of the reflection API (full compatibility within minor releases, best effort towards backward compatibility within major releases, clear replacement path in case of rare incompatible changes in major releases).
The internal module itself (the value that implements InternalApi) isn't defined here, in scala.reflect.api.Universe, but is provided on per-implementation basis. Runtime API endpoint (scala.reflect.runtime.universe) provides universe.compat: InternalApi, whereas compile-time API endpoints (instances of scala.reflect.macros.Context) provide c.compat: ContextInternalApi, which extends InternalApi with additional universe-specific and context-specific functionality.

An extractor class to create and pattern match with syntax ReferenceToBoxed(ident). This AST node does not have direct correspondence to Scala code, and is emitted by macros to reference capture vars directly without going through elem.
For example:
var x = ... fun { x }
Will emit:
Ident(x)
Which gets transformed to:
Select(Ident(x), "elem")
If ReferenceToBoxed were used instead of Ident, no transformation would be performed.

trait WeakTypeTag[T] extends Equals with Serializable
If an implicit value of type WeakTypeTag[T] is required, the compiler will create one, and the reflective representation of T can be accessed via the tpe field.
If an implicit value of type WeakTypeTag[T] is required, the compiler will create one, and the reflective representation of T can be accessed via the tpe field. Components of T can be references to type parameters or abstract types. Note that WeakTypeTag makes an effort to be as concrete as possible, i.e. if TypeTags are available for the referenced type arguments or abstract types, they are used to embed the concrete types into the WeakTypeTag. Otherwise the WeakTypeTag will contain a reference to an abstract type. This behavior can be useful, when one expects T to be perhaps be partially abstract, but requires special care to handle this case. However, if T is expected to be fully known, use scala.reflect.api.TypeTags#TypeTag instead, which statically guarantees this property.

final case class OverloadedArgProto extends internal.SymbolTable.ProtoType with internal.SymbolTable.SimpleTypeProxy with Product with Serializable
Lazily compute expected types for arguments to overloaded methods.
Lazily compute expected types for arguments to overloaded methods. Primarily to improve parameter type inference for higher-order overloaded methods.
Normally, overload resolution types the arguments to the alternatives without an expected type. However, typing function literals and eta-expansion are driven by the expected type:
- function literals usually don't have parameter types, which are derived from the expected type;
- eta-expansion right now only happens when a function/sam type is expected.
Now that the collections are full of overloaded HO methods, we should try harder to type check them nicely.
(This paragraph is conceptually true, but not a spec.) To avoid breaking existing code, we only provide an expected type (for each argument position) when:
- there is at least one FunctionN type expected by one of the overloads: in this case, the expected type is a FunctionN[Ti, ?], where Ti are the argument types (they must all be =:=), and the expected result type is elided using a wildcard. This does not exclude any overloads that expect a SAM, because they conform to a function type through SAM conversion
- OR: all overloads expect a SAM type of the same class, but with potentially varying result types (argument types must be =:=)
- OR: all expected types collapse to the same type (by =:=, pushing down method type params to arguments types)
We allow polymorphic cases, taking account any instantiation by the AntiPolyType prefix. Constructors of polymorphic classes are not supported (type param occurrences use fresh symbols, hard to relate to class's type params).
In all other cases, the old behavior is maintained: Wildcard is expected.

A type function or the type of a polymorphic value (and thus of kind *).
A type function or the type of a polymorphic value (and thus of kind *).
Before the introduction of NullaryMethodType, a polymorphic nullary method (e.g, def isInstanceOf[T]: Boolean) used to be typed as PolyType(tps, restpe), and a monomorphic one as PolyType(Nil, restpe) This is now: PolyType(tps, NullaryMethodType(restpe)) and NullaryMethodType(restpe) by symmetry to MethodTypes: PolyType(tps, MethodType(params, restpe)) and MethodType(params, restpe)
Thus, a PolyType(tps, TypeRef(...)) unambiguously indicates a type function (which results from eta-expanding a type constructor alias). Similarly, PolyType(tps, ClassInfoType(...)) is a type constructor.
A polytype is of kind * iff its resultType is a (nullary) method type.

Note: This is currently a destructive operation on the original Tree. Trees currently assigned a symbol in from will be assigned the new symbols without copying, and trees that define symbols with an info that refer a symbol in from will have a new type assigned.

Creates a tree that selects a specific member sym without having to qualify the super.
Creates a tree that selects a specific member sym without having to qualify the super. For example, given traits B <:< A, a class C <:< B needs to invoke A.$init$. If A is not a direct parent, a tree super[A].$init$ would not type check ("does not name a parent"). So we generate super.$init$ and pre-assign the correct symbol. A special-case in typedSelectInternal assigns the correct type A to the super qualifier.

def checkKindBounds0(tparams: List[Symbol], targs: List[Type], pre: Type, owner: Symbol, explainErrors: Boolean): List[(Type, Symbol, KindErrors)]
Check well-kindedness of type application (assumes arities are already checked) -- @M
Check well-kindedness of type application (assumes arities are already checked) -- @M
This check is also performed when abstract type members become concrete (aka a "type alias") -- then tparams.length==1 (checked one type member at a time -- in that case, prefix is the name of the type alias)
Type application is just like value application: it's "contravariant" in the sense that the type parameters of the supplied type arguments must conform to the type parameters of the required type parameters:
- their bounds must be less strict
- variances must match (here, variances are absolute, the variance of a type parameter does not influence the variance of its higher-order parameters)
- @M TODO: are these conditions correct,sufficient&necessary?
e.g. class Iterable[t, m[+x <: t]] --> the application Iterable[Int, List] is okay, since List's type parameter is also covariant and its bounds are weaker than <: Int

def existentialAbstraction(tparams: List[Symbol], tpe0: Type, flipVariance: Boolean = false): Type
A creator for existential types.
A creator for existential types. This generates:
tpe1 where { tparams }
where tpe1 is the result of extrapolating tpe with respect to tparams. Extrapolating means that type variables in tparams occurring in covariant positions are replaced by upper bounds, (minus any SingletonClass markers), type variables in tparams occurring in contravariant positions are replaced by upper bounds, provided the resulting type is legal with regard to stability, and does not contain any type variable in tparams.
The abstraction drops all type parameters that are not directly or indirectly referenced by type tpe1. If there are no remaining type parameters, simply returns result type tpe.

Given a set rawSyms of term- and type-symbols, and a type tp, produce a set of fresh type parameters and a type so that it can be abstracted to an existential type. Every type symbol T in rawSyms is mapped to a clone. Every term symbol x of type T in rawSyms is given an associated type symbol of the following form:
type x.type <: T with Singleton
The name of the type parameter is x.type, to produce nice diagnostics. The Singleton parent ensures that the type parameter is still seen as a stable type. Type symbols in rawSyms are fully replaced by the new symbols. Term symbols are also replaced, except for term symbols of an Ident tree, where only the type of the Ident is changed.

Declares that this is a runtime reflection universe.
This means that we can make certain assumptions to optimize the universe. For example, we may auto-initialize symbols on flag and annotation requests (see shouldTriggerCompleter below for more details).
On the other hand, this also means that usage scenarios of the universe will differ from the conventional ones. For example, we have to do additional cleanup in order to prevent memory leaks: http://groups.google.com/group/scala-internals/browse_thread/thread/eabcf3d406dab8b2.

def rawToExistential: TypeMap
The raw to existential map converts a raw type to an existential type.
The raw to existential map converts a raw type to an existential type. It is necessary because we might have read a raw type of a parameterized Java class from a class file. At the time we read the type the corresponding class file might still not be read, so we do not know what the type parameters of the type are. Therefore the conversion of raw types to existential types might not have taken place in ClassFileParser.sigToType (where it is usually done).
