Can we have Brainfuck/Intercal/Befunge/Java and other obscure and unpopular languages please?
Nope. Well, not in the general sense. I quite like the idea of having one-off weird-language contests, but I doubt we'll be adding any more "popular" languages.
The next step are challenges where you get scored on your output as well as your code size. For example, imagine a Towers of Hanoi challenge - You'll be scored on the number of moves your code requires to complete the puzzle as well as the code size itself. Having this as an option opens a whole bunch of challenges we can't currently support (meaningfully, anyway.)
Of course, any thoughts from you golfers out there are welcome!
odd language lovers can try http://www.spoj.pl their judge software supports about 40 languages. only a handful of their problems (out of hundreds) are golf though.
