Haskell
<language> (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).
