R7RS Scheme Progress Report

John Cowan recently gave a talk on the progress of R7RS (slides), the next revision of the Scheme language standard, at LispNYC. After the R6RS debacle, the community stepped back and is now basing the next standard on R5RS; the work has been split into two languages — R7RS-Small and R7RS-Large. The first working group is preparing to issue a final draft of the R7RS-Small language (PDF; clocking in at 73 pages vs. R5RS's 50) within the next few weeks. Read on for a summary of the planned changes to R7RS (more or less in the order of presentation).
