I think this use case is important enough to implement it immediately. 
However, since the moratorium is currently in place for Python, would it be 
ok to fork Python 3 to integrate it into the language? I propose Mython as 
the name of the fork. I also propose to drop the entire Subversion history, 
so that we can start using Mercurial instantaneously. That will greatly 
improve the freedom of Mython as a language.
