Haskell is a general-purpose, statically-typed, purely functional programming language with type inference and lazy evaluation. Designed for teaching, research and industrial application, Haskell has pioneered a number of advanced programming language features such as type classes, which enable type-safe operator overloading. Haskell’s main implementation is the Glasgow Haskell Compiler (GHC). It is named after logician Haskell Curry.
