#11243: Flag to not expand type families -------------------------------------+------------------------------------- Reporter: crockeea | Owner: Type: feature request | Status: new Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: 7.10.2 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 crockeea): Please! That would (likely) solve the issue reported in this ticket. I can't find a ticket where the solution was to expand type families, perhaps someone else recalls the reason for that choice? I wonder if a more granular approach might be warranted. Perhaps we could say `-fno- print-expanded-type-families -fprint-tf NextListElt` to *only* expand `NextListElt`? I don't have a concrete use case for this off the top of my head, but if some people want TFs to be expanded, it seems like there should be some sort of intermediate solution. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11243#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
