Although I think it is acceptable to make on-the-fly compilation more expensive in order to allow ahead-of-time compilation, we should not do it gratuitously. It will be a long way until we might no longer want to care about the on-the-fly compiler since everybody compiles their important code ahead-of-time anyway. So, cleaning up the existing lazy memoizer is a very good thing indeed. But I'd say you should also make sure that you don't significantly lose performance by doing it. That part of Guile will be performance-critical for quite some time. -- 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
