#9127: Don't warn about pattern-bindings of the form `let !_ = rhs` -------------------------------------+------------------------------------ Reporter: refold | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by simonpj): Harump. Maybe `let _ = rhs` ''should'' trigger a warning! It's dead code after all. But the `let !_ = e in b` means just {{{e `seq` b}}} so I suppose you could argue that it non-warnable. Does anyone else care? Simon -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9127#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
