If python starts going all paranoid schizoid on us, the few
remaining holdovers from the good old days will be choosing
another language. But don't worry Steven, even if i find a
new favorite language, i will always drop in preiodically to
say hi. ;-)

Nope. Even the though the most hated software developer in
history offers a compatibility mode for their users, Python
does not. Python's philosophy is that you will accept
Python3, or you will suffer...

As for myself, i'm waiting for Python4. I will skip right
over Python3. I say, let the other saps to suffer the
migration headaches, because i don't need them. I'm too busy
getting stuff done.
