Prima :-)

It seems more logical to have __file__ set, even for frozen modules (after all, if it's there in a code object's co_filename, is there some reason it shouldn't be exposed as a module attribute? (Even though it isn't at the moment.)

Well, I guess passing in a reference to the module would suffice. The
function could then look around for functions, methods, etc. to find
a usable code object.

I agree that having a __file__ attribute in frozen modules would
be helpful, since it's obviously not widely known that this
attribute does not always exist (just grep the stdlib as example,
in particular the test suite).

The module object's PyModule_GetFilenameObject() even reports a missing
__file__ attribute as a SystemError.

Perhaps something to discuss on python-dev.
