Via Grant Rettke over at Wisdom and Wonder I found these slides from a talk at LispNYC by John Cowan on September 13. As readers from my old blog will recall, R7RS will be split into a “small Scheme” and a “large Scheme” with the small version being a modest expansion of R5RS and the large version being more like R6RS but still downward compatible with the small version.
Working Group 1 (WG1) is tasked with the small Scheme and has almost completed its work. Cowan expects the final committee draft to be out in a few weeks and after formal comments the final version. Working Group 2 is a subset of WG1 and has pretty much suspended their work until WG1 is completed.
Very often it’s hard to make sense of the slides from a presentation without having heard the actual talk. In this case, however, the slides stand alone very well and are quite informative. If you’re interested in Scheme and want to know what’s coming up, take a few minutes to look through them.
