[lmud-devel] re-inventing past mistakes

Your reasoning for LMUD sounds very much why I love using eshell for
Emacs.  Having shell operations implemented in Emacs allows you to swim
in a 'soup' of elisp functions as if they were shell-scripts/commands.
It's a very powerful paradigm and takes absolutely no time even for
newbie non-lispers to 'get it'.  Amazing.  

This really brings up questions regarding the complexity of interacting
with a MUD.  I mean with today's machines, who really MUDs on a VT100
anymore?  I personally use tkmoo simply because it allows me programatic
control over the windowing operations in that I can break up the stream
of chatter/interaction into well defined "channels" each in their own
window.  Rolling all of this in CL would be a dream-come-true, heck I'll
make it my login shell.  :-)

And yes, although Mooix does allow multi-language objects, it aspires to
be no more complex than LambdaMoo, which is an "interesting" language
lacking in many features which are the strength of CL.  However, it does
work and seems to be relatively little effort to port without
re-implementing systems functionality within CL.

So I'm actually giving Mooix a go and am quite impressed with acl-compat
for the networking layer.  I've successfully read a website over socket
connectinos using both CLisp and LispWorks (on Debian) so I expect that
it's claims of near-universal Lisp communication are not unfounded.

Hope all goes well with your studies and I'd like to see something in
the CVS repo ASAP, if anything just for the pure joy of playing with a
broken CL MUD.  I'd also like to [eventualy] include this in the Lisp
Resource Kit when it gets into a stable state.
