#15962: Type family & typeclass interaction suppresses errors -------------------------------------+------------------------------------- Reporter: madgen | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: ⊥ Component: Compiler (Type | Version: 8.4.3 checker) | Keywords: TypedHoles, Resolution: | newcomer Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple error/warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by RyanGlScott): * keywords: type family, typeclass, error message => TypedHoles, newcomer Comment: Interesting program. It's conceivable that this was fixed by Tritlo's recent work on typed holes (possibly commit 39de4e3d33dd9879398062620ad00b1e3b8481ce, although I haven't confirmed this). It //is// fixed now though, thankfully. In any case, I can't recall having a test case quite like this one (the test case from #15321, which the aforementioned commit fixed, requires Template Haskell), so it might be nice to add this as a test case as well. Any volunteers? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15962#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
