Decorator syntax for type casting in decorators

[emmeowzing]

I don't know if this is the proper way to write this, but I was writing a decorator and thought, wait, if I can use functools.wraps as a decorator, why can't I use typing.cast as a decorator? I understand it's meant to be as fast as possible, but I'm sure decorating as in the following kind of way wouldn't slow things down too much. Also, I'm really just hoping to start the discussion, because I haven't been able to find anything about it on GitHub or by Googling.

Thanks! I think this looks like a duplicate of something already being discussed @declared_type, see python/peps#242 and python/mypy#3291. Normally, opening an issue before a PR would save some efforts.

Okay I'll remember that next time!

I am closing this since since this still needs discussion (which can continue in the issues mentioned in my previous comment).
