#9242: Implement {-# OVERLAPPABLE #-} and {-# INCOHERENT #-} pragmas -------------------------------------+------------------------------------- Reporter: simonpj | Owner: diatchki Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.8.2 Component: Compiler | Keywords: Resolution: | Operating System: Unknown/Multiple Differential Revisions: | Type of failure: None/Unknown Architecture: | Test Case: Unknown/Multiple | Blocking: Difficulty: Unknown | Blocked By: | Related Tickets: | -------------------------------------+------------------------------------- Comment (by simonpj): As I say on the other ticket, I think it'll be a hard sell to ''replace'' overlapping instances with instance chains. So I'd still really like to get the per-instance `{-# OVERLAPPING, OVERLAPPABLE #-}` pragmas proposed above. Would you still be willing to do that? Or, if not, would someone else?
