Qi is a functional programming language that offers the advantages of pattern matching, l calculus consistency, optional lazy evaluation and static type checking. It uses sequent calculus notation to define types, and has the most powerful type system of any existing functional language, including ML and Haskell. Qi includes an integrated fully functional Prolog and an inbuilt compiler-compiler. Qi includes sources and is absolutely free for personal and educational use.
