#15849: Error message: "Perhaps you need a let in a do block", when there is no do block. -------------------------------------+------------------------------------- Reporter: cdsmith | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.4.3 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- This code: {{{#!haskell main = return () foo = return () }}} Gives the error message: {{{ parse error on input ‘=’ Perhaps you need a 'let' in a 'do' block? e.g. 'let x = 5' instead of 'x = 5' }}} But this isn't in a do block. It would be awesome if GHC checked whether there's a do block before giving a suggestion that depends on there being a do block. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15849 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
