To answer Ben's mail as well, the "No" would be more of the "don't do
it". My answer was as argued as Terry's one anyway (it was quite intended).
Steven, you often use analogies/similarities, here's one:
A: "My wheel is flat"
B: "Buy a new car"
Buying a new car would solve A's problem : yes
Should A buy a new car : probably no
Python 3.2 is fine, but someone could run into several issues while
migrating. This is quite a pretty huge decision to make (I dedicate this
sentence to Rick, I hope he's trolling fine).
