#7783: MultiWayIf should start a new layout --------------------------------------+------------------------------------ Reporter: exbb2 | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.8.1 Component: Compiler (Parser) | Version: 7.6.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: #4359 --------------------------------------+------------------------------------ Comment (by Simon Marlow ): In [changeset:aab65608f9a26990b2c5083e4b65b9d1f6c9b48a/ghc]: {{{ #!CommitTicketReference repository="ghc" revision="aab65608f9a26990b2c5083e4b65b9d1f6c9b48a" Add layout to MultiWayIf (#7783) This makes it possible to write x = if | False -> if | False -> 1 | False -> 2 | True -> 3 Layout normally inserts semicolons between declarations at the same indentation level, so I added optional semicolons to the syntax for guards in MultiWayIf syntax. This is a bit of a hack, but the alternative (a special kind of layout that doesn't insert semicolons) seemed worse, or at least equally bad. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7783#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
