I've done stuff like this too. What I was pointing out was mostly composing
selectors from strings. One great way to tell e.g. ME that a message
actually is sent somewhere when doing these kinds of shenanigans is to
write an SUnit test which includes the composed selector. Then it will
still show up as being sent, and I'll know not to remove the method from my
image as useless.

Make sense, gents? :)
