Ponder
A non-strict polymorphic, functional language by Jon Fairbairn
Ponder's type system is unusual. It is more powerful than the Hindley-Milner type system used by ML and Miranda and extended by Haskell. Ponder adds extra recursive 'mu' types to those of Girard's System F, allowing more general recursion. Surprisingly, the type system and type inference algorithm are still not completely understood.
