#9049: Expose srcLoc from the assertion architecture to allow better error messages -------------------------------------+------------------------------------ Reporter: nh2 | Owner: Type: feature request | 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 simonmar): I actually like the wiki:ExplicitCallStack/ImplicitLocations idea, I'm just worried that if we have it then we'll have people who want location- abstracted versions of all the partial functions in base, and that's a lot of extra clutter. If we could provide the feature but draw the line at using it in APIs (except for `error`, `undefined`, `throw`, and other things that explicitly raise exceptions) then I'm all for it. I realise that then you don't get automatic `head []` locations. But it doesn't stop someone from defining their own location-abstracted `head`, or indeed making a package of location-abstracted partial functions from base. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9049#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
