Editing Clean (programming language) (section)

==Features==
Clean shares many properties and [[Syntax (programming languages)|syntax]] with a younger sibling language, [[Haskell]]: [[referential transparency]], [[list comprehension]], [[Guard (computing)|guards]], [[Garbage collection (computer science)|garbage collection]], [[higher order functions]], [[currying]], and [[lazy evaluation]]. However, Clean deals with mutable state and [[input/output]] (I/O) through a [[uniqueness type]] system, in contrast to Haskell's use of [[Monad (functional programming)|monads]]. The [[compiler]] takes advantage of the uniqueness type system to generate more efficient code, because it knows that at any point during the execution of the program, only one reference can exist to a value with a unique type. Therefore, a unique value can be [[destructive update|changed in place]].<ref name="CleanHaskellGuide">{{Cite FTP |url=ftp://ftp.cs.ru.nl/pub/Clean/papers/2007/achp2007-CleanHaskellQuickGuide.pdf |server=ftp.cs.ru.nl |url-status=dead |title=FTP link }}</ref>

An [[integrated development environment]] (IDE) for [[Microsoft Windows]] is included in the Clean distribution.
