I can't say right now how to fix this, but in general, I think the whole syntax transformer business needs to be redone for a separate memoizer/compiler pass. That is, it is OK when your new evaluator breaks the existing syncase and this is not easily fixed. We need to find a fix eventually, but that fix should also remove the kluginess of the current situation completely. In my vision, the syntax transformer in essence _is_ the memoizer. Thus, I'd say it is acceptable that syntax-case support must be redone from the ground up. -- GPG: D5D4E405 - 2F9B BCCC 8527 692A 04E3 331E FAF8 226A D5D4 E405 _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://mail.gnu.org/mailman/listinfo/guile-devel
