I meant it's not really clear what the developer should do here. Not use
callee-cleanup parameters (they may not know what that is), not export the
class? I suppose the realistic option is don't use inheriting constructors.
I suppose warning is better than a link-time failure though, but making it a
separate group would be nice.
It would be cool if we could fix this though. I wonder if we have more gaps
like this (missing thunk capabilities) and if the improved tail call support
over the years has made it possible to fill those gaps.
