Problem is described here: http://stackoverflow.com/a/6416333/239247 Summary:

Proposal: from __future__ import abs__file__
Anatoly, this subject was already discussed on this list, just three months ago, in a thread you started! [1]_
To quote one of Nick Coglahan's replies [2]_:
Note that any remaining occurrences of non-absolute values in __file__ are generally considered bugs in the import system. However, we tend not to fix them in maintenance releases, since converting relative paths to absolute paths runs a risk of breaking user code.
We're definitely *not* going to further pollute the module namespace with values that can be trivially and reliably derived from existing values.
This was also changed in Python 3.4 back in October: http://hg.python.org/cpython/rev/76184b5339f2
Thanks. That's just what I was looking for - a status update. Links in emails are not telling anything about progress being made, roadmap, problems and versions of Python. Seem like tracker is a poor tool to track this stuff too.
Now in spite of recent Python 3 status update, the question is how possible to make this feature more visible and implemented in previous version as from __future__ import abs__file__?
I'd like to ask for two perspectives: 1. technical feasibility 2. political obstacles (backward compatibility policy / process obstacles), even if they are obvious
Also, what is the process of nominating this features to selection in Python 2.8 (or whatever comes out of this incremental development idea)?
So, three questions with ideas in total. -- anatoly t.
