OK, I'm done refactoring the syntax stuff. Hopefully it's a little easier to follow now. I didn't make any major changes to the syntaxing, just rearranged it to make the interfaces clearer and to improve readability some. One major change you did make was to eliminate the history tracking. Although none of the system exploited this, and although there was some extra complexity in the bookkeeping for this, I often found it invaluable for debugging macros. It would have been even nicer to teach the debugger about this so that we could have an expansion stepper like the one in DrScheme that I have heard people rave about. _______________________________________________ MIT-Scheme-devel mailing list [email protected] http://lists.gnu.org/mailman/listinfo/mit-scheme-devel
