I would be happy to contribute to this if that would be useful for type
checkers like pytype, although like Guido I don't think the current text of
the PEP is ambiguous. Typeshed already has a set of lint rules that limit
what can be put in stub files, but it could be useful to communicate the
exact set of allowed constructs.

There has already been a long discussion on the typing issue tracker that
resulted in no consensus for any change to the current recommendation.
Perhaps there is something we can do, but it's not clear to me what that
would be.
