Wrote code in all but Piet, so knew it was not glsl. I must spend way too much time behind a computer as i also knew all besides Piet even if it was not multiple choice :)

I do think it should be harder; like when you get a lesser known language, also add the choice for others; APL + K + J for instance, or worse (for many) K or J showing either.

C vs C++ vs D.

Prolog vs Haskell vs Ocaml. Curveball there could be something like Mercury.

Haskell vs Purescript.
