I'm having a problem with the proposed implementation. I haven't found
any mention of it, so apologies if this has already been discussed:

>>> from flufl.enum import *
>>> class C(Enum):
...  a = 1
...  b = 2
>>> C.a.__class__
<class 'flufl.enum._enum.EnumValue'>
>>> isinstance(C.a, C)
>>> isinstance(C(1), C)

It would really be better if instances were actual instances of the
class, IMO.
