I definitely see two issues here, a short term one and a long term one. I was currently focused on the former, i.e. how do we get (ice-9 regex) to have invariant behavior across platforms. I completely agree that this still leaves open the very interesting question, "what would a good regex SRFI do?". With respect (ice-9 regex), I'm inclined to agree with you. If we can include a good POSIX implementation, then that should fix the problems I've been asking about. Thanks again for the very interesting comments. -- Rob Browning rlb @defaultvalue.org, @linuxdevel.com, and @debian.org Previously @cs.utexas.edu GPG starting 2002-11-03 = 14DD 432F AE39 534D B592 F9A0 25C8 D377 8C7E 73A4 _______________________________________________ Guile-user mailing list Guile-user@gnu.org http://mail.gnu.org/mailman/listinfo/guile-user
