I'm not sure which use of the word "mapping" you're talking about. PEP 3115 is explicit that there is no specific requirements for the __prepare__()'d namespace; it just mentions some things that might be useful to have in such an object. So, in order to replace it with a view or something, we'd want to change the PEP to explicitly document what is required. Personally, I'd just as soon make it explicitly official that locals() in a class suite gives you the __prepare__()'d object, whatever it is. If a given Python implementation can support PEP 3115 in the first place, then it clearly knows what object to return. ;-) _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
