Ultralisp: A fast-moving Common Lisp software distribution
Slightly tangential, but I wish some Lisp would make a serious comeback and challenge mainstream languages. For this purpose, libraries are essential. So better tooling would help, and that's why Ultralisp and Quicklisp are interesting.<p>Clojure is very nice. I have used it for several projects. But sometimes I would prefer not to rely on Java libraries so much, and cleaner stack traces.<p>Racket may get some critical momentum now, with the whole merge with Chez.<p>I don't have high hopes for a Common Lisp implementation, as the ecosystem has become too fragmented and stagnant. But I wish I could be surprised here. Shen introduced some great ideas to make a powerful static typing an option in Lisp [1].<p>[1] <a href="http://www.shenlanguage.org/" rel="nofollow">http://www.shenlanguage.org/</a>
