LGTM, with one minor nit:

> +                              (not (consp l)) ; SEXP is a dotted list
> +                              ;; Is SEXP is of a form like (ELT... . ,X) ?

The "Is SEXP is" part seems to have one "is" too many...

I suggest

  Does SEXP have a form like (ELT... . ,X) ?

Thanks.
