I released a new version of iterate today. It fixes a bug in synonym code, removes spurious WARNINGs on perfectly good code, and adds a README (the same as the iterate page) and a BUGS file (find the current version on the iterate bugs page). Get it at http://boinkor.net/lisp/iterate/iterate-current.tar.gz. The signature is at http://boinkor.net/lisp/iterate/iterate-current.tar.gz.asc.
