You may want to look at the MUQ server. It is NOT a LambdaMOO server, so
this may not be close to what you're interested in, but MUQ does have
support for conventional programming languages, explicitly including
Common Lisp. It's also extensible in this sense, in that you can readily
(I'm told) define your own compiler to compile a conventional language
into MUQ code.
An information page can be found at
The following is a section from this page that covers support for
Muq bytecode compilers are implemented in-db using an assembler class
that handles most of the busywork and guarantees production of only valid
executables, allowing new compilers to be written by unprivileged users.
Muq already supports a variety of popular programming syntaxes including
a large and growing subset of Common Lisp which should eventually be a
complete, compatible implementation, allowing you to port code back and
forth and to take advantage of existing code libraries. If your syntactic
religion isn't supported yet, it is not hard to add a compile for it as
well, probably starting with one of the existing ones.
At the semantic level, the Muq virtual machine provides just about
everything you've heard of, and some things you may not have, including
vanilla functions, generic functions, anonymous functions, promises with
implicit forcing (in Scheme nomenclature -- a substrate suitable for
experimenting with functional programming), thunks (something vaguely
like named pipes in unix), semaphores for mutual exclusion, implicit job
blocking on bounded streams, and sophisticated exception handling
