(Named after the logician Haskell Curry) A lazy purely functional language largely derived from Miranda but with several extensions. Haskell was designed by a committee from the functional programming community in April 1990. It features static polymorphic typing, higher-order functions, user-defined algebraic data types, and pattern-matching list comprehensions. Innovations include a class system, systematic operator overloading, a functional I/O system, functional arrays, and separate compilation.

Haskell 1.3 added many new features, including monadic I/O, standard libraries, constructor classes, labeled fields in datatypes, strictness annotations, an improved module system, and many changes to the Prelude.

Gofer is a cut-down version of Haskell with some extra features.

Filename extension: .hs, .lhs (literate programming).

A functional programming language named after American logician Haskell Curry. Haskell was developed by a group of researchers in the 1980s who were alarmed at the number of different functional languages being developed. Haskell adheres more to all the principles of functional programming than other languages but is considered challenging to write. First released in 1990, there are several implementations of Haskell, the Glasgow Haskell Compiler (GHC) being the most prominent. See functional programming and programming language.
