@api annotation (or something to mark `FunctionX`-es that should not be transformed to `MiniboxedFunctionX`)

[VladUreche]

scala> class api extends annotation.StaticAnnotation with annotation.TypeConstraint
defined class api

scala> def doSomethingWith[T](f: T => T @api) = f
doSomethingWith: [T](f: T => T @api)T => T @api

This should not be later transformed to:

doSomethingWith: [T](f: MiniboxedFunction1[T, T] @api)MiniboxedFunction1[T, T] @api

This is subsumed by the bridges generated automatically following bug #135.

Or maybe not: if you're not overriding anything from outside, no bridge is generated. So it's a valid issue.
