(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).
