While I'm largely a disinterested bystander, it occurs to me that if you look at the reasons behind wanting enumerations in the first place, you might find a good reason to defend this view. For example, if enumerations are intended to reduce the likelihood of certain types of errors (where the use of typical XXXX=3 "constants" might be more prone to errors), then perhaps this suggests that passing errors silently is bad. That is, trying to compare enumerations that should not be compared *is* an error (raising an exception) *because* the whole point of enumerations is to avoid errors in such cases. Or perhaps I'm off the mark as to why people want enumerations. Is it just a cosmetic consideration? (Yes, I've used and appreciated them extensively in C and might even pick up Enum for my Python code... I'm just sort of playing devil's advocate here.) -Peter -- http://mail.python.org/mailman/listinfo/python-list
