Subject: Possible way to get loop-aware subclassable Futures
Currently, $loop->new_future returns an instance of a loop-specific Future subclass. This does not play well with custom subclasses in libraries built on top of IO::Async. One possible way out of this, which should maintain back-compatibility, is: * Future->new can take a 'await' coderef param, and its 'await' method just delegates to it - existing subclasses keep working, because they override the method * Loop->new_future passes something like await=>$self->curry::_await_future to the $future_class->new call - older Future classes should just ignore it - newer Future classes will store it but not use it because loop-specific classes still override the method * Loop->new_future can take a class name or a factory fuction, and use it instead of the $future_class - no existing code passes anything to new_future, so this can't break client code * at this point we can stop defaulting the $future_class to a loop-specific subclass, and just use Future * document the whole thing, and we're done It may even work!
