And, oh yeah, grokking continuations makes it a lot clearer how generators, iterators, exceptions and coroutines work. One concept which subsumes all the others. And if you want to get into compiler construction, understanding CPS conversion makes it much easier to do code transformations. There's just tons of research which went into Lisps, because it's such a nice vehicle for language experimentation. There's half a century of research going into Lisps. Other languages haven't been around for that long, so I suppose there's something to find in Lisp history for everyone, but it might not be the same thing for everyone!
