Thanks, we needed a set of problems to start with and we've used some Euler problems as the basis even thought we slightly changed the problems to be more generic (the input is unknown) so that users are forced to write a generic solution.

Could you add a Prolog, too? GNU Prolog or SWI would be good.

Sure, we can add any language that have an open source compiler/interpreter. I've added Prolog to our backlog. Stay tuned!
