  The Scala Reflection API (located in scala-reflect.jar).

  In Scala 2.10.0, the Scala Reflection API and its implementation have an "experimental" status. This means that the API and the docs are not complete and can be changed in binary- and source-incompatible manner in 2.10.1. This also means that the implementation has some known issues.

  The following types are the backbone of the Scala Reflection API, and serve as a good starting point for information about Scala Reflection:

  - scala.reflect.api.Symbols
  - scala.reflect.api.Types
  - scala.reflect.api.Mirrors
  - scala.reflect.api.Universe

  For more information about Scala Reflection, see the Reflection Guide

  EXPERIMENTAL

  This trait provides support for scopes in the reflection API.

  A scope object generally maps names to symbols available in a corresponding lexical scope. Scopes can be nested. The base type exposed to the reflection API, however, only exposes a minimal interface, representing a scope as an iterable of symbols.

  For rare occasions when it is necessary to create a scope manually, e.g., to populate members of scala.reflect.api.Types#RefinedType, there is the `newScopeWith` function.

  Additional functionality is exposed in member scopes that are returned by `members` and `decls` defined in scala.reflect.api.Types#TypeApi. Such scopes support the `sorted` method, which sorts members in declaration order.
