Hmm.... Have you been sneaking looks at python-list again, Guido ? :-) I'm
certain the expanding of IMPORT would make a lot of people very happy. Alex
Martelli only just discovered the fact you can populate sys.modules
yourself, with non-module objects, and was wondering about its legality and
compatibility.

I, for one, am very +1 on the idea, also on MAL's idea to do our best in the
IMPORT_STAR case (try dict.items(), etc.)
