Views were previously proposed as an extension to Haskell 1.3. Wadler's proposal is still on the web here. Related ideas include PatternGuards.


Another related idea is PatternSynonyms, proposed (most recently, at least) by Conor McBride on the Haskell' list. Unimplemented, though, and thus probably not for Haskell'. But if views are given serious consideration, then so should PatternSynonyms.
