WOW, I love partition. In all the instances that weren't a simple "in" test I ended up using [r]partition. In some cases one of the returned strings gets thrown away but in those cases it is guaranteed to be small. The new code is usually smaller than the old and generally clearer. Wow. That's just beautiful. This has now convinced me that dumping [r]find() (at least!) and pushing people toward using partition will result in pain in the short term (of course), and beautiful, readable code in the long term.

note that partition provides an elegant solution to an important subset of all problems addressed by find/index.

just like lexical scoping vs. default arguments and map vs. list comprehensions, it doesn't address all problems right out of the box, and shouldn't be advertised as doing that.
