I see the issue of whether it's a built-in or part of the standard library as being a detail. My personal opinion is that they're important enough to be built in, but having to write "import enum" (or whatever) won't kill me. If making it a builtin becomes a point of contention, drop it and concentrate on the more key issues of how enums will behave. -- http://mail.python.org/mailman/listinfo/python-list
