Python tip: 3.2 adds a memoization decorator

This is a really handy thing to have around, in case you've got expensive computations that you want done more than once. I've written a clumsier version of this myself, once or twice -- but it makes sense to have in the standard library!

There's some other neat stuff in the functools package too: currying and reducing. Pretty slick!
