#11243: Use Type Synonyms to Compress Errors -------------------------------------+------------------------------------- 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): I believe both of the major replicated blocks are due to type families. The `PrimePower` block is due to singletons, which makes heavy use of type families. Ideally, it would say something more like `PrimePower (PP (N7, N1))`. The `NextListElt` block also comes from a type family: while the type list itself is a simple type synonym, `NextListElt` is a type family. In that case, I'd like to see `NextListElt * zq MyTypeList`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11243#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
