Bug report

Python enum fails equality test against itself after reloading using importlib.reload

Suppose we have a module:

# mod_enum.py

import enum

class E(enum.Enum):
    A = 'A'

In a Python shell:

>>> import importlib
>>> import mod_enum
>>> old_enum = mod_enum.E.A
>>> id(old_enum)
140661148711472
>>> importlib.reload(mod_enum)
<module 'mod_enum' from 'mod_enum.py'>
>>> new_enum = mod_enum.E.A
>>> id(new_enum)
140661156076320
>>> old_enum == new_enum
False

Your environment
