I was interested in Lisp due to some AI systems (namely Maxima but there are more), and had an idea to use it with Perl together.

It appears that Lisp do not play nice embedding games (except ECL, which is embeddable Lisp) but still embedding is possible.

I've created Language::Lisp module on CPAN which currently stale (but is better on my local copy)
may be I'll release better version sometimes soon...
