Can't find module 'contextlib.AbstractContextManager'

[NeilGirdhar]

The following line gives an error: from contextlib import AbstractContextManager. AbstractContextManager has been in Python since version 3.6.

This is caused by the parser not re-exporting names that come from the typing module:

pytype/pytype/pyi/parser.py

Line 716 in 2f97d0a

if from_package != "typing" or self._ast_name == "protocols":

. Should be a quick fix.

Apparently mypy only re-exports names that have an "as" clause, e.g.

from typing import ContextManager as ContextManager

python/mypy#2927
python/typeshed#2727

This has been fixed, pending the next pytype release (this Friday if all goes well).

Wow, that was fast!!
