#15539: Regression since 7.10.3, "variable not in scope" errors sometimes get buried under a sea of much less relevant errors. -------------------------------------+------------------------------------- Reporter: Wizek | Owner: (none) Type: bug | Status: closed Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.3 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: | rename/should_fail/T15539 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by simonpj): * status: new => closed * testcase: => rename/should_fail/T15539 * resolution: => fixed Comment: Good point, thank you. An oversight in `TcErrors`. (The bug only shows up for top level errors. If you say even this: {{{ foo :: forall b. String foo = show a where a = baz }}} which puts the `Show a` constrain under an implication, then the error is suppressed already. It just wasn't happening for constraints that had no enclosing implication. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15539#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
