The fact that Py3K will be a "big cleanup" release is not new - it has 
been clear for some years now that this would be the first release that 
would break compatibility. Still GvR and the team seem to be making 
their best to not avoid as much breakage as possible, clearly document 
what will break, and if possible provide tools to ease migration.

I've been using Python since 1.5.2 and had no problem yet with upgrades. 
I couldn't say so of some proprietary languages I've used, where each 
minor release could potentially break something - not talking about 
major ones that were certified to imply a full rewrite (and I'm not 
talking of something as easily scriptable as replacing print statements 
with a function or method call).
