Yes, I'm sure: we need a PEP first. Ideally it would answer some of the questions raised above, and it would lay out the class hierarchy.
Maybe I wasn't clear enough: Of course we need a PEP for these names, their intended meaning as object category abstraction and interface placeholder. Too late for Python 2.2, but probably a nice project for 2.3. -- Marc-Andre Lemburg CEO eGenix.com Software GmbH ______________________________________________________________________ Consulting & Company: http://www.egenix.com/ Python Software: http://www.lemburg.com/python/
