I'm told that there are several public versions of symbolics-loop-like
macros floating around... none of them exactly right, but pretty close.

You might want to check out the "iterate" package supplied with the PCL
version of CLOS.  It's easily extensible, well integrated with the
standard CL iteration constructs, far more lisp-like than SMBX loop, and
optimizes nicely.  Sadly, there's not much documentation...
