#10833: Use injective type families (decomposition) when dealing with givens -------------------------------------+------------------------------------- Reporter: jstolarek | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 7.10.2 checker) | Keywords: TypeFamilies, Resolution: | InjectiveFamilies Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #6018, #11511, | Differential Rev(s): #12199 | Wiki Page: | -------------------------------------+------------------------------------- Comment (by nfrisby): This scenario seems like an excellent use-case for a typechecker plugin: so that power users could opt-in to the soundness conjecture. Do we have an estimate of if that's possible give current TC plugin API and how complicated it would be to implement? Thanks. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10833#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
