I have some experience using both those libraries. Ghuloum's library is written in R6 scheme. It works fine out of the box, but I had some difficulty in modifying it to export some of Gambit's extensions. As for Andre's, his will not work out of the box with Gambit. I worked with him on creating a compat-gambit.scm so that it will work with Gambit. I've put it all up as a tarball at http://smyles.com/gambit-r6rs.tgz if you want to give it a go. I have a bit of documentation on how it works if you search for "R6RS" on Gambit's wiki. I think you'll find Andre's design very interesting for your project since it's written in R5 and is built out of a simpler core. His website has more details and you should check out his comments on comp.lang.scheme. As far as the state of R6 on Gambit, it works great but the system is still rough. I've not only exposed Gambit's extensions as libraries, but I'm also able to create my own libraries, including libraries that use Gambit's ffi. There still plenty to do so if any of you are interested in hacking on it let me know. I plan on making an update to the tarball in a couple of days. Arthur Ken Dickey wrote:

You probably know of the two major syntax system implementations for R6RS, both of which deal with renaming, but just in case...
