This list has always been somewhat tech centered, or should I say
tech-loving? Granted I have never got any close to PCCTS than looking at
somebodyelse's use of it, but the output was less intelligible than a
(not widely accessible) OO parser system I have used. The caveat with
any such system is that you have to learn them and their potential
weirdnesses.

If speed isn't paramount and you don't need the most complicated grammar
in the world then I wonder if not a recursive decent parser combined
with a fairly direct OO representation for execution would do wonders
for many MUDserver startups.

Ola.
