As for the convenience angle, I totally agree; I'd actually settle for set-*! or *-set! if they were standardized, but they're not and probably won't. Now that I think about it, there is a good reason to prefer setf to set-*!; it is far easier for a macro (particularly define-syntax macros) to generate (setf (some-arbitrary-form ...) ...) than to somehow symbol munge set-some-arbitrary-form! into something define-syntax will accept. This isn't as much of an issue for a CL style defmacro, but a CL style defmacro is ugly in Scheme for various reasons. -- Graham Hughes <ghughes@cs.ucsb.edu> PGP Fingerprint: 36 15 AD 83 6D 2F D8 DE EC 87 86 8A A2 79 E7 E6
