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? |
