#12382: Rename clasing type variables more consistently -------------------------------------+------------------------------------- Reporter: nomeata | Owner: Type: feature | Status: new request | Priority: low | Milestone: Component: Compiler | Version: 8.1 (Type checker) | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- This is minor polishing, but polish is nice: Consider {{{ :t (id,id,id) (id,id,id) :: (a -> a, a1 -> a1, a2 -> a2) }}} this looks as if the first `a` is in some way better or more important. What I’d like to see is {{{ :t (id,id,id) (id,id,id) :: (a1 -> a2, a2 -> a2, a3 -> a3) }}} In other words: If two type variables clash and need to be renamed, then rename both (all) of them. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12382 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
