I'd like to endorse the approach taken by Clojure (the other Closure)
too. It is a dialect of Lisp that where a central design decision was
to make almost all data structures immutable. This obviates most of
the need for locking, a common performance issue for multi-threaded
programs. It is easy to write programs that rarely use shared,
mutable data structures. And when you do need shared, mutable data
structures, the locking is explicit. Take a look at a
http://clojure.blip.tv/file/1313398/ for an introduction to Clojure
for Lisp programmers. I wasn't expecting much, but it's really good.
Someone could define a version of Common Lisp with these characteristics...
