[Python-Dev] 2to3 speedup patch

Thu Mar 20 20:56:30 CET 2008

Under the instruction of Martin, I've made some small changes to 2to3 
so keeps track of which fixers act on which level of node. The 
speedup isn't too shabby: running on the example file, processing 
time went from 9 to 7 seconds, and the test suite dropped from 400 to 
350.
I have attached the hacky, ugly, proof-of-concept patch to http:// 
bugs.python.org/issue2431
If there's no reason not to implement this sort of thing, I'll clean 
it up and commit it when I get home (or something).
