Haskell is an advanced purely functional programming language. The product of more than twenty years of cutting edge research,
it allows rapid development of robust, concise, correct
software. With strong support for integration with other languages,
built-in concurrency, debuggers, profilers, rich libraries and an active
community, Haskell makes it easier to produce flexible, maintainable
