n-body requires updating a global array of double values to be
I think the array and any side-effects on it can and should be local to the simulation procedure.
competitive performance-wise, though we haven't really nailed this benchmark yet. The current entry should be considered an older approach to raw performance -- typically we can get good (or better) results in using the ST monad.
As I understand, a function can use ST, but still be pure. If so, that's the version I'd like to time (assuming it's also type-safe). The only pure functional solution on that page that I found claims to have a huge leak.
