The same goes for LET-TRANSFORMER and LETREC-TRANSFORMER. Huh? This is the what DEFINE-SYNTAX _already_is_! I don't care if a couple implementations hardwire SYNTAX-RULES into DEFINE-SYNTAX; that can easily be fixed, just as easily as introducing a new definition form for macros. What you propose here is _exactly_ what I _already_ suggested, except that I used the existing DEFINE-SYNTAX.
