Thanks to Andreas Waldenburger, THC4k (http://stackoverflow.com/

their tips. I was able to find solution:

Hello,
I need to implement such behavior:
obj.attr1.attr2.attr3 --> obj.attr1__attr2__attr3
obj.attr1.attr2.attr3 is parsed as ((obj.attr1).attr2).attr3,
so this cannot work in general but only if attr1 and attr2 are known to
not be 'final' names.

Hello,
I need to implement such behavior:
obj.attr1.attr2.attr3 --> obj.attr1__attr2__attr3
It looks like I have to override obj's class __getattribute__ and also
use python descriptors somehow.
Any help will be much appreciated.
