Excellent! While it certainly can't hurt to implement functions in C and I am sure you know this already, I still want to point out that avoiding non-tail-recursive behavior does of course not imply having to code the thing in C. So, when spotting a non-tail-recursive function that should be tail-recursive, the easy thing would be to change the Scheme code. One does not need to recode it completely in C. Just something that I thought of. -- 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
