package scala.annotation

/**
 * This annotation configures how Scala prints two-parameter generic types.
  *
  * By default, types with symbolic names are printed infix; while types without
  * them are printed using the regular generic type syntax.
  *
  * Example of usage:
  {{{
    scala> class Map[T, U]
    defined class Map

    scala> def foo: Int Map Int = ???
    foo: Map[Int,Int]

    scala> @showAsInfix class Map[T, U]
    defined class Map

    scala> def foo: Int Map Int = ???
    foo: Int Map Int
  }}}
  *
  * @param enabled whether to show this type as an infix type operator.
