#13476: Coercion maching in RULES is fragile -------------------------------------+------------------------------------- Reporter: simonpj | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): Your Plan B means to take the `kco` parameter to `unify_ty` and do the same thing at the term level. Perhaps the precise code in `unify_ty` could be improved, but the idea is a good one, and you're propose to replicate this action on coercions. I think it's all the right direction. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13476#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
