Ask HN: CL implementation of Haskell's Quickcheck

Aside from Marco Baringer's FiveAM, I don't know of any Common Lisp test suite that has support for spec testing ala Haskell's Quickcheck. I think this is a great concept for testing no? Clojure seems to have this in the form of Reid Draper's Simple-check test suite.

Any pointers to CL resources that deal with this would be greatly appreciated.
