Hello,
recently I wrote a small library that uses an Enum. That worked as

I don't think Python anywhere defines that a enum will be a singleton,
and you should be checking for equality (==) not identity (is)
If you're not sure, please do a little research first. We have enough bad
information on the 'nets already.

I should have mentioned the cyclic dependency -- if two modules import each

Hello,
recently I wrote a small library that uses an Enum. That worked as
expected. Then I added a main() and if __name__ == "__main__" to make it
runable as script. Now Enum members that should be the same aren't
identical any more, there seem to be two instances of the same Enum.
