This was all hashed out in gory detail on python-ideas. I feel strongly that
base EnumValues should be unordered, especially because the underlying values
can be of any type. What would you expect to happen in this case:
class X(Enum):
a = 1
b = 'hi'
if X.a < myvalue < X.b:
# whaa?
I would expect the same behaviour from enums that I get in Python 3 from
non-enums. That is, if enums X.a and X.b happen to both be ints, or both
strings, then comparisons should succeed, but if they are different types, I
should get a TypeError.
The above applies to related enums. If they are unrelated (e.g. Colours.red <
Insects.ant) then I think TypeError is appropriate.
