[Python-Dev] Add an ExecutionLoader abc to importlib or to runpy?

[Brett Cannon]

I implemented get_filename() as specified in PEP 302 for importlib's source
and bytecode loaders and I was starting to create the ABC for importlib.abc,
but then I realized that perhaps the loader should live in runpy instead of
importlib.
Putting the new ABC in importlib keeps all PEP 302 ABCs in a single spot.
But this addition to the PEP 302 protocols is very specific to runpy and is
not directly required to make imports work (the implementation was just a
reshuffling of pre-existing code from one method to another). I am tempted
to leave the ABC out of importlib and stop at implementing get_filename()
for importlib.abc.PyLoader and PyPycLoader.

Any opinions?
