#8095: TypeFamilies painfully slow -------------------------------------+------------------------------------- Reporter: MikeIzbicki | Owner: bgamari Type: bug | Status: new Priority: high | Milestone: 8.2.1 Component: Compiler (Type | Version: 7.6.3 checker) | Resolution: | Keywords: TypeFamilies Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: 5321 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): It somehow didn't make it onto the ticket, but there was a concern about this idea: once you omit coercions from one module, then all downstream modules are also missing (some) coercions. This means that `-dcore-lint` doesn't do nearly as much as it normally does. That makes me a bit uncomfortable, but perhaps it's OK. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8095#comment:23 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
