    Code to deal with macros, namely with: * Compilation of macro definitions * Expansion of macro applications

    Code to deal with macros, namely with: * Compilation of macro definitions * Expansion of macro applications

    Say we have in a class C:

    def foo[T](xs: List[T]): T = macro fooBar

    Then fooBar needs to point to a static method of the following form:

    def fooBar[T: c.WeakTypeTag] // type tag annotation is optional (c: scala.reflect.macros.blackbox.Context) (xs: c.Expr[List[T]]) : c.Expr[T] = { ... }

    Then, if foo is called in qual.foo[Int](elems), where qual: D, the macro application is expanded to a reflective invocation of fooBar with parameters:

    (simpleMacroContext{ type PrefixType = D; val prefix = qual }) (Expr(elems)) (TypeTag(Int))

case class MacroImplBinding(isBundle: Boolean, isBlackbox: Boolean, className: String, methName: String, signature: List[List[Fingerprint]], targs: List[Global.Tree]) extends Product with Serializable

Represents all the information that a macro definition needs to know about its implementation. Includes a path to load the implementation via Java reflection, and various accounting information necessary when composing an argument list for the reflective invocation.
