#11549: Add -fshow-runtime-rep -------------------------------------+------------------------------------- Reporter: goldfire | Owner: goldfire Type: bug | Status: closed Priority: highest | Milestone: 8.0.1 Component: Compiler | Version: 8.1 Resolution: fixed | Keywords: TypeInType Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D1961 Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): Mmm, this is a good point. My first thought here was to look for kind errors in specified type arguments and provide the user with a better error (including the full type of the applied function) in the case of a unification error. Austin and I discussed this and he suggested that perhaps `-XTypeApplications` should imply `-fprint-explicit-runtime-reps`. This sounds reasonable (if a bit surprising) at first glance given how likely it is that you will experience `RuntimeRep` arguments with `TypeApplications`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11549#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
