The current PEP text doesn't specify; that's an omission on my
part. The answer should be "yes, an enum can be tested for
membership".
I'll add that to the specification.

Not specified as having one, no.

You can do the same thing more elegantly by explicitly querying the
attributes of the enumeration::
>>> day = 'sun'
>>> print getattr(Weekdays, day)
sun
