Haskell is a modern, general-purpose, pure functional programming language that combines many powerful results from research into a practical programming language. Its features include:

  • Static typing, which increases robustness by allowing the compiler to catch many common errors automatically.
  • Type inference, which deduces types automatically and frees the programmer from writing superfluous type signatures.

Haskell comes with many libraries, freely available compilers for almost any computer, debuggers, profilers, code coverage and testing tools.

  • Videos of the Haskell Workshop 2007 talks and discussion are now available again (on a different host to previously). They are in QuickTime (H264 video, AAC audio) format, at 320x240 pixels, low frame rate (but still about 120Mb per half-hour talk).
  • is a mentoring organisation in the 2007 Google Summer of Code. 9 students have been funded by Google to work on infrastructure projects for Haskell.
  • The Haskell-prime committee has started work on defining the next minor revision of the language specification.
