#16203: Unhelpful names for wildcard type variables -------------------------------------+------------------------------------- Reporter: simonpj | Owner: goldfire Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.6.3 Resolution: | Keywords: | PartialTypeSignatures 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 goldfire): Suppose we have {{{#!hs type family F a b where F _ _ = Bool }}} If we reverse the change, I believe we get that GHC reports that the equation is `F w1 w2 = Bool`. Perhaps that's better than what we have, but someone has to pay the price. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16203#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
