CLISP's LOOP macro is a CLtL1 loop, a simple loop.

The (LOOP FOR var ...) constructs use the CLtL2 loop macro. I have an
implementation of it, but I don't distribute it with clisp because I
discourage the use of LOOP as long as the ANSI CL draft has inconsistencies
in its specification.

It is on ma2s2.mathematik.uni-karlsruhe.de:
