I've updated my R6RS package for Gambit. 1. Implemented err5rs records as an R5RS as well as R6RS library 2. Changed expander.scm and runtime.scm to use the new record system. 3. Updates for the compile script The latest tarball is available at: http://smyles.com/projects/r6gambit.tar.gz The project homepage is now http://smyles.com/projects/r6gambit The darcs2 repository is available at http://smyles.com/projects/r6gambit/darcs The err5rs records implementation can be independently used for your projects. Just copy the files: err5rs-records-inspection.scm err5rs-records-procedural.scm Arthur
