#393: functions without implementations -------------------------------------+------------------------------------- Reporter: c_maeder | Owner: simonpj Type: feature | Status: new request | Milestone: ⊥ Priority: normal | Version: None Component: Compiler | Keywords: (Type checker) | Architecture: Unknown/Multiple Resolution: None | Difficulty: Moderate (less Operating System: | than a day) Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Changes (by maeder): * cc: maeder@… (removed) Comment: Wow, I've created this ticket 9 years ago and I got used to live without this feature, although it should be simple to implement. (I hope my old username c_maeder was deleted.) To answer your question. Yes, source file and line number should be included (indicated by "or whatever") Adding source file and line number to the Exception for `undefined` is obviously not so easy. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/393#comment:22 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
