And what a wonderful day that will be! Reading any piece of code you 
didn't write yourself -- or wrote a long time ago -- will be an 
adventure! Every script will have it's own exciting new set of keywords 
doing who knows what, which makes every script nearly it's own language! 
Oh joy, I cannot wait!

That's sarcasm, by the way.

Then I can write code like:

for for in in:
    while while:
        if if:
            raise raise

which will go a long way to ensuring that my code is an hostile and 
unreadable as possible.

(Sometimes, less can be more. That's especially true of programming
