Mark Shannon <m...@hotpy.org> added the comment: PEP 526 explicitly states "as with all dunder attributes, any undocummented use of __annotations__ is subject to breakage without warning"
I consider deleting __annotations__ to be undocumented use. Do you really think that an obscure difference in the behaviour of >>> class C: ... del __annotations__ ... x: int justifies an extra bytecode, but the implicit return at the end of all functions (LOAD_CONST None; RETURN_VALUE) does not? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32550> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
