  I wouldn't call this straightforward:

fibs = 0 : 1 : zipWith (+) fibs (tail fibs)

  Short? Yes. Clever? Yes. Easy for a non-haskell-programmer
non-mathematically-oriented person to understand? No.

  (The curious thing about that is that it's easy to convince a layman
that it works, but the more (procedural) programming you know, the harder
it will be to understand *why* it works (and isn't, for example, an infinite
recursion that never terminates, as there doesn't seem to be any kind of
termination condition). Also understanding why it procudes the correct
result may be difficult.)

  That's the whole idea.

  I don't recall OpenGL requiring that many pointers either. Just tons
of straight function calls.
