;;; note: Tests 3 through 6 are commented out since they all contain

;;;       Common Lisp and I don't have time to figure out why.

;;; Problems with LOOP:
;;;  1. Symbolics implementation of LOOP expands directly into RPLACD without
;;;     going through SETF. This foils the LOCAL declaration.
;;;  2. Results disappear upon ALL-VALUES internal backtracking.
;;;  3. Lucid expands LOOP into a MULTIPLE-VALUE-CALL.
