If the answer to that is "yes", then the next question is, what's the best way to accomplish this while retaining the existing API for backward compatibility?

This is a clear case for lazy imports; perhaps something like this in email/init.py:

import sys

class LazyImporter(object): def init(self, module_name): self.__module_name = module_name

def getattr(self, name): import(self.__module_name) mod = sys.modules[self.__module_name] self.dict.update(mod.dict) return getattr(mod, name)

sys.modules["email.MIMEText"] = LazyImporter("email.mime.text") ...
