I can submit a PR. Just making sure I understand, is this essentially the
desired behavior change?
import weakref
import functools
if 0:
from test.support import import_fresh_module
functools = import_fresh_module('functools', blocked=['_functools'])
@functools.lru_cache
def f(x):
return x
ref_to_f = weakref.ref(f)
print(ref_to_f)
# Current:
# TypeError: cannot create weak reference to 'functools._lru_cache_wrapper'
object
# Desired:
# <weakref at 0x000001ABFE0F5090; to 'function' at 0x000001ABFE2D5AF0 (f)>
