#9173: Better type error messages -------------------------------------+------------------------------------ Reporter: simonpj | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by nomeata): Despite the very general ticket title, let’s not confalte multiple errors. The original ticket was a about a type mismatch (inferred vs. expected). The example by schlyer is about an ambiguous type in the GHCi prompt. Note that with some more instances added, `map 1 [1..5]` would type check! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9173#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
