I don't have time, unfortunately. So other folks can pick this up.
I don't remember if I made any progress on this - will post whatever I have if
I find something.

Eli, did you ever make any progress with this? Anything you can post so
someone else can run with it if you don't have time?

Eli Bendersky added the comment:
I'm (somewhat) back looking at this. Should the first step be
sys.get_calling_module_name()? I can provide a patch. Re its name, perhaps the
long name isn't that bad given that this is a rather obscure API. But
suggestions for something shorter/better will be

Guido van Rossum added the comment:
As I explained in issue 17947, I think that any Python implementation worth its
salt should be able to implement sys.get_calling_module_name() (*), at least
for the case where the caller is top-level code in a module body. That is a
much weaker requirement
New submission from Nick Coghlan:
(Split off from issue 17947)
collections.namedtuple includes a frame hack that attempts to make the
functional API work for ordinary module level assignments:
try:
result.__module__ = _sys._getframe(1).f_globals.get('__name__',
'__main__')

Ethan Furman added the comment:
I believe Guido will be happy to replace the frame hack once we have something
better, such as a way to implicitly (or explicitly in the case of helper
functions) pass the calling module's name.
Maybe a global __calling_module__ that a function can look at...
Nick Coghlan added the comment:
Right, but I think it's categorically impossible to make that work reliably
without new syntax and a name binding protocol (or something equivalent).
Due to the existence of the global keyword, the frame stack and normal
assignment syntax simply don't provide
Nick Coghlan added the comment:
Oops, that was supposed to be definitive assignments in my previous comment.

Brett Cannon added the comment:
If you read the docs for sys._getframe()
(http://docs.python.org/3/library/sys.html#sys._getframe) we explicitly state
that the function should be considered an implementation detail for CPython.
While Nick doesn't want to argue from the VM angle, I will.
