Haskell is a computer programming language designed by a committee in 1990 to consolidate the best features of the many purely functional programming languages that were created in the late 1980s. Haskell is thus neither a procedural programming language nor an object-oriented one, although it offers monads such as do to support procedural programming and classes with inheritance to support object-oriented programming (there is also a variant of Haskell called O’Haskell which includes more support for object-oriented programming). In general, Haskell programs are most naturally written declaratively.
The standard version of the language is Haskell 98; Haskell 2007 hasn’t been released yet but is expected to be only a minor revision of Haskell 98.
