  EXPERIMENTAL

  EXPERIMENTAL

  The base package for Scala macros.

  Macros are functions that are called by the compiler during compilation. Within these functions the programmer has access to compiler APIs. For example, it is possible to generate, analyze and typecheck code.

  See the Macros Guide on how to get started with Scala macros.

-  abstract class Universe extends api.Universe

  EXPERIMENTAL

  EXPERIMENTAL

  The refinement of scala.reflect.api.Universe for the use by macro writers.

  This universe provides mutability for reflection artifacts (e.g. macros can change types of compiler trees, add annotation to symbols representing definitions, etc) and exposes some internal compiler functionality such as `Symbol.deSkolemize` or `Tree.attachments`.
