[Python-ideas] Proposal to extend PEP 484 (gradual typing) to support Python 2.7

[Jim Baker]

FWIW, we now fully support both Jedi and lib2to3 in Jython 2.7.1 master.
With some other work this weekend, we should be releasing 2.7.1 beta 3 and
then shortly a RC - we just fixed the last blocking bug.
