Years ago (early '70s) there was a tranlator called Mlisp from
Stanford that translated an Algol-like syntax into Lisp 1.6.  You
might look at that.  The source used to be available and there was a
tech report describing it.  The downside of using it was that all
debugging was still in the destination (i.e. lisp w/ parens)
language.  Unless you allow debugging in the source language I
don't think that your customers will be very happy.
Show them LOOP.  That almost looks like a c/pascal :-).

Also, from time to time there have been read macros that translate infix
arithmetic expressions to lisp-type prefix ones.  I don't have any
pointers for those.

The plisp/glisp/mlisp set was ported to MCL 1.3.x by somebody at Apple and 
was available on one of the Developer CD's.  It had some
minor dependency on Object Lisp, if I remember right.
