Mercury

Mercury is a purely declarative functional logic programming language geared towards real-world applications. It is related to both Prolog and Haskell. It features a strong, static, polymorphic type system, as well as a strong mode and determinism system.

Mercury has several back-ends, Low-level C, High-level C, Java, Erlang, and C#.
