[FEATURE] Should Enum be considered immutable by default? #98
Description
Is your feature request related to a problem? Please describe.
I was surprised to learn that deepfreeze(Enum.VALUE) produced a frozendict(Enum.VALUE.__dict__). I expected it to return the enum. E.g.:
>>> from enum import Enum
>>> from frozendict import deepfreeze
>>> Color = Enum('Color', ['RED', 'GREEN', 'BLUE'])
>>> deepfreeze(Color.RED)
frozendict.frozendict({'_value_': 1, '_name_': 'RED', '__objclass__': <enum 'Color'>})Describe the solution you'd like
Consider making Enum.VALUE an immutable scalar by default.
Describe alternatives you've considered
I know I can register a custom conversion:
>>> from enum import Enum
>>> from frozendict import deepfreeze
>>> Color = Enum('Color', ['RED', 'GREEN', 'BLUE'])
>>> deepfreeze(Color.RED, custom_converters={Enum: lambda x: x})
Color.REDor
>>> from enum import Enum
>>> from frozendict import deepfreeze, register
>>> Color = Enum('Color', ['RED', 'GREEN', 'BLUE'])
>>> register(Enum, lambda x: x)
>>> deepfreeze(Color.RED)
Color.REDAdditional context
While I understand this can be easily configured on my end via the register function I'm wondering if it makes more sense to treat enums as immutable scalars by default.
