Hi,

I observed that loop has a strange behaviour:

> (setq ii 0)
0
> (loop foo foo  (incf ii) foo (when (> ii 10000) (return)))
NIL

doesnt give any error despite foo isn't bound to anything

> foo
Error: The variable FOO is unbound.

Why is that? Is it a bug or is something I do not know about loop?
