Lili has gone a long way since release 011.
The new version (021) is significantly faster (2.5-3x faster than JScheme 1.4) and supports some nice new features like pattern-matching, lexical closures (although principally dynamically scoped), and implicit closuring.
Work on a documentation is in progress. See littlisp.sourceforge.net for an under-construction-homepage.
Unfortunately Lili has became a one-person project. Any help would be great!
