I don't know about super-programs, but I use Clojure at work (doing things no one else would ever care about) and I use it at home to solve fun problems. I previously did the same things in PHP and Perl and Ruby and Python and such, and the Clojure versions are easier to write and maintain, easier to use, less code, more fun etc. Same for Common Lisp, generally.

I wouldn't extrapolate beyond that. I don't know what languages are good for writing super-programs since I never wrote one. Super-programs are a small subset of all programs.
