Is Hector a Lazy TA or Haskell Specific?

Hector is a lazy implementation of these easy TAs, right? And we really builds on the power of laziness. If you want to enumerate all students' SAT problems and just finding a single one, I've actually think you probably could write an efficient solver using East TA's. The data structure itself is straight. So this in this technique is it like Haskell only specific or you can implement it even for other languages like OCaml? Not at all, Hasselb's effect.
