Nope, I'm seeing clasp for the first time -- Christian Schafmeister's talk was extremely nice to listen to!

I did come across some small LISP implementations at the early stages, but by that time I already had the AST builder done. Maybe because I didn't actively search for LISP implementations, as I didn't need a 'proper' LISP per se, more of a DSL for quickly writing ASTs of arbitrary complex computational expressions. Those ASTs were the final goal ; )
