[[project @ 2003-06-09 11:22:14 by simonpj] simonpj**20030609112214 Remove duplicate infix type-con section (thanks to Ross P) ] { hunk ./ghc/docs/users_guide/glasgow_exts.sgml 637 - - Infix type constructors - -GHC supports infix type constructors, much as it supports infix data constructors. For example: - - infixl 5 :+: - - data a :+: b = Inl a | Inr b - - f :: a `Either` b -> a :+: b - f (Left x) = Inl x - - -The lexical -syntax of an infix type constructor is just like that of an infix data constructor: either -it's an operator beginning with ":", or it is an ordinary (alphabetic) type constructor enclosed in -back-quotes. - - -When you give a fixity declaration, the fixity applies to both the data constructor and the -type constructor with the specified name. You cannot give different fixities to the type constructor T -and the data constructor T. - - - - }
