blackbox restriction #1: can't refine the official return type
When an application of a blackbox macro expands into a tree `x`,
the expansion is wrapped into a type ascription `(x: T)`, where `T` is
the declared return type of the blackbox macro with type arguments and
path dependencies applied in consistency with the particular macro
application being expanded.
This invalidates blackbox macros as an implementation vehicle
of type providers.
