Ah, macro and varargs. You might take the "cheap" cop-out
and decree that your macro takes *one list* as argument
instead of a variable number of arguments. You'd be in good
company there (cf. the `let' special form). If you're a
perfectionist, more work might be involved (I've no ready
solution for you at the moment, sorry)
