No such magic is available for an= y other form of sys.path entries. So while you can add a urlimport object to sys.path, you lose the hook when you convert the object to a string, as nobody will recreate the hook.

Don't like that -- a lazy and incremental replacement method seems much m= ore sensible, and preserves the semantics that non-python-dev-subscribers (an= d I) desire.
