Check for example this code:
http://shootout.alioth.debian.org/u64q/program.php?test=pidigitslang=clojureid=1
It is slower than scala 8 (!!!) times.
But peppering it with types can easily bring it on par with java/
scala.
Any takers ?

I suspect that most of the time is spent in BigInteger math in that
particular program. If so, type annotation won't speed that up.
Glad to be proved wrong, though!

If the Clojure program also used that library, it should be as fast, or
nearly so, as any other program that uses the same algorithm and the GNU GMP
I've not followed the benchmarking game much at all, but it surprises
me that implementations are allowed to use native libraries at all.
I figure that there must have been some discussion/debate around this
somewhere at some point, but a few minutes of googling yielding
nothing interesting.
Here is a brief discussion from January 2011:
