But this only really works for complete module replacements, not modules like pickle where only key portions have been rewritten (which happens more often than the complete rewrite). A slight change would make it work for modules where only key functions have been rewritten. For example, pickle.py could read: from _pypickle import * try: from _pickle import * except ImportError: passTrue, although that still suffers from the problem of overwriting things like __name__, __file__, etc.
What do you mean overwriting __name__ and __file__? Doing import * in a pure Python file doesn't override these.
