Lambda the Ultimate

The first draft of the R7RS small language standard is now available at:

http://trac.sacrideo.us/wg/attachment/wiki/WikiStart/r7rs-draft-1.pdf

This is a relatively small revision to the R5RS, adding many of the most frequently requested features but keeping the overall structure of the report the same, with a current count of 67 pages. In the spirit of the older reports, many situations are left as errors or unspecified, leaving room for implementations to experiment with their own extensions. The language is still small enough to provide a very compact implementation of, and the current development branch of Chibi-Scheme provides all of the functionality of the draft (in some cases with different names or modules, pending finalization of the standard).
