Oooh, I've not come across that before. *furiously shortens solution some
more*

Which brings me to one of the things I think was really useful: the standard
library, particularly Enumerable / Array / Hash, is full of neat methods.
 It's definitely worth going back and reading over the docs for those to see
what there is beyond #each, #map, and #inject.

I already knew this, but it's always worth repeating.  The one problem, in
terms of shortest solution at least, is that often the method names are a
tad long.
