Common Lisp LOOP

[Michael Ginn <GINN@sumex-aim.stanford.edu>]

     Has anyone written a LOOP macro for common lisp?  Most of the common
lisps I use, besides the Symbolics and TI versions, have no definition at all
for LOOP.  (In Steele's book, LOOP is mentioned only as a future possibility
for extension of the common lisp specification).  

     Most specifically, I'd like to use it in KCL and in Post-Penultimate
Common Lisp, but of course any definition conforming to the specification
would probably work.
