How about: [xnip] That's not bad. This conflates all enumerated items into a single namespace whereas the metaclass solution makes each enumeration its own namespace. For example: plumbers = enum['Fred','John','Bill'] electricians = enum['Fred','Jake','Lester'] Using a metaclass allows you to distinguish Fred the plumber from Fred the electrician. But that may or may not be what one actually wants. Must sleep on it. rg -- http://mail.python.org/mailman/listinfo/python-list
