[Python-Dev] [python-committers] FINAL WEEK FOR 3.7.0 CHANGES!

> But cases not supported before 3.7 (like List[int]) now produce fragile
pickles.

List[int] pickled in 3.7 can't be un-pickled in 3.6, but I wouldn't worry
too much about this because it never worked in 3.6.
I remember you proposed using __getitem__ in __reduce__, but I am not sure
it is a better way, although it will fix the above problem.

I don't think this one is a blocker and we can move this discussion back to
b.p.o., unless you have some particular concerns.

The AST one however looks more serious.
