I can certainly see merit in that idea. The problem is that it's often not clear what the idiomatic style for a particular language applied to a particular problem is. Many of the Haskell solutions also look quite old, predating for example the now standard Haskell "Vector" library.

It's a useful resource, but I think we should we wary of making very general remarks based on the results.

We should we wary of making very general remarks, period.

The benchmarks game is not restricted to "the idiomatic style" so it isn't a problem that "the idiomatic style" for a particular problem is often not clear.

We would be very happy to accept new programs:

Do you mean you agree? Do you mean the statement is possibly self-defeating? Do you mean you noticed the typo? Do you mean…?
