Wasp Lisp: Mosquito, Mach III.

The rather funky Mosquito lisp VM and language has been reborn in a slightly different guise: Wasp Lisp. From the development blog:

Wasp Lisp is a member of the Lisp-1 family, borrowing principles from R5RS Scheme, Python and Erlang. Derived from MOSREF and MOSVM, Wasp Lisp will provide many of Mosquito's features, including extensibility, painless concurrency, and efficient I/O model in an production quality environment.

I hope some of the crypto stuff makes a comeback.

I've been eying it too - since around December of last year. Development has picked up again, but it's still in an early state. Even so, it contains some very good ideas.

The documentation could use an overview of its components, but using the waspdoc utility and browsing through the 'mod' directory reveals a lot.
