I'm not sure I fully follow the scenario where this would happen in practice (i.e., under what practical circumstances would Py_mod_create return an immutable non-module object?) - but if the object doesn't have a __file__, this seems like a reasonable (and consistent) response. __file__ isn't needed at runtime for the Apple Framework loader to operate; and it's passing CI with this change - so I guess it's OK to merge.

@encukou One additional thought - Is this behavior a new feature of 3.15, or does this require back porting to 3.14/13?

[encukou]

I agree it's not immediately practical.

(What is sometimes practical is non-module objects in general. While implementing PEP 793 and testing the edge cases, I used a string to keep the test simple. Guess strings are too simple!)

The behaviour is not new. I don't think it requires backporting, but it's probably better to file off an obscure sharp edge.
