#7633: Checkable "minimal complete definitions" -------------------------------------------------+------------------------- Reporter: shachaf | Owner: Type: feature request | twanvl Priority: normal | Status: Component: Compiler | closed Resolution: fixed | Milestone: 7.8.1 Operating System: Unknown/Multiple | Version: 7.6.1 Type of failure: None/Unknown | Keywords: Test Case: warnings/minimal/WarnMinimal | Architecture: Blocking: | Unknown/Multiple | Difficulty: | Unknown | Blocked By: | Related Tickets: #6028 -------------------------------------------------+------------------------- Comment (by Lemming): Interested in an experience report? I added MINIMAL pragmas to numeric- prelude classes. I did several mistakes when transferring human description to MINIMAL pragma, mostly mixing up comma and bar. These mistakes were revealed by instances that gave wrong alarms. However one alarm was serious and spotted a missing method implementation in a cycle of default definitions. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7633#comment:53 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
