/**
* 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.
* @since 2.12.2
