final class compileTimeOnly(message: String) extends StaticAnnotation
An annotation that designates that an annottee should not be referred to after type checking (which includes macro expansion).
Examples of potential use: 1) The annottee can only appear in the arguments of some other macro that will eliminate it from the AST during expansion. 2) The annottee is a macro and should have been expanded away, so if hasn't, something wrong has happened. (Comes in handy to provide better support for new macro flavors, e.g. macro annotations, that can't be expanded by the vanilla compiler).
- Value parameters:
the error message to print during compilation if a reference remains after type checking
