The loop language is so complicated and confusing that I never
bothered trying to learn it. I always used simpler primitives to
write loops and it was always enough.

You can't really use that much recursion in Lisp because of the lack
of guaranteed TCO. I think that makes it reasonable to say that
Scheme is a functional language but Lisp is not. ("Functional" = it's
reasonable to code in a style where the only way to connect variables
to values is lambda binding (maybe through syntax sugar), so all loops
are implemented with recursion).
