#11735: Optimize coercionKind -------------------------------------+------------------------------------- Reporter: goldfire | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Fine. In undoing, could you also add the invariants for all Role annotations to the data type itself? * The comment on the constructor NthCo should state the invariant. Given (NthCo r n co) we require that lteRole r (nthRole (coercionRole co) n)) or something like that. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11735#comment:64 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
