is eminently practical to support both Python 2 and Python 3 with a

There have been some recent discussions about that on this list. A few

Benjamin Peterson has even written a library intended to help
programmers who want to do that:

This note to the list is to express my wish for an automated tool
named "2to6" which converts my Python 2.6 codebase to being both py2-
and py2- compatible using Benjamin Peterson's six library.
