There's ALWAYS seems to be a neat way to do what's needed with Haskell.

Well, you can drop the arguments entirely, and let the type be inferred to get
car = head
which is pretty nice. You could use an INLINE hint to make the compiler replace it before compilation, though I don't think it would change performance much...
