There has been a lot of activity recently on the
general subject of Python "type hinting" and "type checking"
with multiple competing syntaxes proposed.

Python 3 already has an obscurely-documented feature [2] allowing
you to annotate function args & result with type expressions.
I think these are compatible with PyQt class names?

There are other existing syntax proposals like Obiwan [3],
typecheck-decorator [4] or Ensure [5].

Guido just put out a semi-formal proposal for a framework [1].
