Can't we do some kind of callable check? There may be some weird decorators that won't work, but they aren't likely to be useful in this context.

Yeah, it may not be as tricky as I feared: adding "not callable(attr_val)" to the conditions for deciding whether or not to convert a class attribute to an instance of the enum would likely suffice to address the method problem.

You couldn't create an enum of callables, but that would be a seriously weird thing to do anyway....

Cheers, Nick.
