I have a few questions about the PEP 328 which I'd like discussed:

* Why do we absolutely need to change the current scheme
   of 'local, then absolute' for name resolution ?

   In the past I have often had the case where I wanted to
   move Python software written as top-level modules into
   their own package. The current logic makes this painless;
   the proposed move to 'absolute only' introduces serious
   editing which is bound to be error-prone.

   I don't object absolute imports at all, but I like the
   possibilitiy to package'ify existing Python module/module
   sets by simply copying them into a newly created package
   directory.

   Note that Python's own name lookup behaviour is very similar
   to the existing import scheme (nested scopes left aside).

* How will the proposed 'absolute only' strategy affect
   the __import__() API ?

   This is of special concern since quite a few applications
   out there rely on __import__() having the existing semantics
   and a change would cause these applications to fail. One
   such instance is the encodings package search function,
   which relies on first looking in the package for a suitable
   codec and then scans for a top-level installation.

* Will the DeprecationWarning only be raised for uses of
   'import xyz' and 'from xyz import a' or also for __import__() ?

* How do these semantics changes affect importers that hook
   into __import__ ? (imputil.py, ihooks.py, etc.)

* What's the affect on zip imports or tools like py2exe,
   McMillan's installer, etc. ?

BTW, is any of this already implemented to play with ?

Thanks,
