Even if Haskell could somehow be proven to be "the better language" (whatever that means), Clojure is still extremely elegant, simple and beautiful, and it has one huge advantage: it runs on the JVM, so it automatically harnesses the vast JVM ecosystem, as well as all of its (unmatched, IMO) monitoring, profiling and runtime-instrumentation tools (+ dynamic class-loading and hot code replacement).
"Frege is a non-strict, pure functional programming language in the spirit of Haskell ... Frege programs are compiled to Java and run in a JVM. Existing Java Classes and Methods can be used seamlessly from Frege."
True, but it's in the same camp, where "elegant" and "I have to write parentheses all the time" are two different concepts, and, and this was the point, it can use the JVM libraries. (in a type safe manner, btw)
