+1 from me too, especially 2.3 is a royal pain in the ass. I want my
any, all, decorators and I want my str.partition and even str.rsplit.
I also can't run 2.3 on my system as it won't compile, so it always
makes my hudson red. I'm also pretty ok with 2.4 if anyone wants to
keep it, but would certainly not mind dropping it.
