#16246: GHC HEAD-only Core Lint error with unboxed equality (Non-CoVar has coercion type) -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.10.1 Component: Compiler | Version: 8.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: #15648 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): OK, to be clear then, your proposal is that: * `CoVars ` must have `(~#)` types * But non `CoVars` can have `(~#)` types too Is that what you are saying? That's ok with me. But `core-spec/` would need updating to reflect this. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16246#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
