Is there a real use case for @property? Otherwise, if we're going to mess with module's getattro, it makes more sense to add getattr, which would have made Nathaniel's use case somewhat simpler. (Except for the dir thing -- what else might we need?) One additional (IMO quite strong) argument in favor of module level getattr is that this is already used by PEP 484 for stub files and is supported by mypy, see https://github.com/python/mypy/pull/3647

So we're looking for a competing PEP here. Shouldn't be long, just summarize the discussion about use cases and generality here.
