If I have (on sys.path), a directory "x" containing a "y.py" module, and 
later (on sys.path), another directory "x" containing a "y.py" module, 
what is "from x import y" supposed to do?

OR

If I have (on sys.path), a module "x.py" containing, say:

    y = 5

and later (on sys.path), another module "x.py" containing, say:

    y = 6

what is "from x import y" supposed to do?


I guess I don't see how this new proposal makes anything more confusing 
than it already is?
