Interesting talk on Python vs. Ruby and how he would like Python to have just a bit more syntactic flexibility.

Step away from the keyboard! This is a programmer's arrest!

There are laws around here, laws that we can't allow to be broken.
You've just broken 12 of them. You think the laws don't apply to you,
huh, punk? HUH?

I'm sentencing you to three months HARD LABOR in Ruby for that code
you just wrote. And if you think it's too harsh, then I'll sentence
you to NINE MONTHS PHP and see how you feel about that!
