[issue22116] Weak reference support for C function objects

[Stefan Behnel]

Stefan Behnel added the comment:

Patch looks ok. Not sure about the test dependency from test_weakref.py to _testcapi, though. Is that module allowed to be used everywhere? Wouldn't it be enough to test that one of the builtin functions is now weak referencible? "len" seems to be used in other places, for example.
