If you move x.py to x/__init__.py, it does *exactly the same thing* 
in current versions of Python:

Python 2.7.1 (r271:86832, Nov 27 2010, 18:30:46) [MSC v.1500 32 bit 
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
 >>> from x import y
 >>> import x.y
 >>> x.y
<module 'x.y' from 'x\y.py'>
 >>> y
5

The PEP does nothing new or different here.  If something is baffling 
you, it's the behavior of "from ... import", not the actual importing process.

"from x import y" means "import x; y = x.y".  The PEP does not 
propose we change this.  ;-)
