(runpy is also a lot happier with them when they expose get_filename(), a relatively recent addition to the PEP 302 API). An addition I was not even aware of. Looks like importlib needs a little updating.
Yes, I didn't notice that sneak into PEP 302, either :-)
I probably should have been noisier about that when I added it. I'm pretty sure it did come up on this list, but it would have been somewhere in the middle of a runpy discussion: runpy was stuck because it only uses PEP 302 to *find* the modules it needs, but not to actually load them. In the original version of PEP 302 the only way to get a loader to tell you the filename was to load the module and see what it set __file__ to, which wasn't useful in the runpy case. If I recall correctly, at the time when PJE was rationalising the code duplication between runpy and pkglib the comment was also made that runpy's get_filename() optional loader extension should be mentioned in PEP 302. runpy still works for loaders that don't provide it, it just can't set __file__ or sys.argv[0] correctly in those cases.
