I'd like to second this suggestion -- I've run into this problem a few
times. When you're using a listcomp or genexp, you can inline it of
course, but especially with a lot of functions growing the incredibly
convenient key= arguments in 2.5 (e.g. min, max and the deque
functions if I recall correctly), methodcaller would be a much more
duck-typing friendly way to create such callables.
