- Paul Graham posted his talk to this year's ILC, Some work on ARC, a progress report on the Arc language. I'm sorry to see he didn't cosider Alan Bawden's approach to first-class macros, but I guess it wouldn't have fitted in with his overall approach. And I guess the value of this is that it does make clear what his approach is.
- The proceedings of last month's Scheme workshop are available, including the interim report of the R6RS editors committee. It looks like Flatt's PLT/MzScheme module system is going to be the basis for evaluating module systems; and agreeing to a module system is the first task the R6RS committee have set themselves; for a partial introduction to the issues there's a summary of module systems by David Rush from 2001.
