(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.
[Version 1.2: SIGPLAN Notices 27(5), Apr 1992].
