Right. 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.
