Indeed! And I'd be quite content with such a solution, since I
consider scripts and modules to be distinct.
And here I've been busily blurring that distinction for years ;)
(actually, the whole "name == '__main__'" idiom meant the distinction
was already pretty blurry long before I got involved)
I take it the concrete proposal here is if the filename of a new
module matches either __main__.__file__ or __main__.__cached__, then
that module should be ignored completely for import purposes allowing
a module with the same name later on sys.path to be found?
An explicit error being raised instead would be just as good.

I'm not sure I like that, I'd be more inclined to just return the
__main__ module in that case rather than letting the search continue
further down sys.path (although I agree the current semantics of
getting two copies of the same module under different names in this
case are less than ideal).
Cheers,
Nick.
