#15559: fromJust has no HasCallStack -------------------------------------+------------------------------------- Reporter: nomeata | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: 8.6.1 Component: Core Libraries | Version: 8.4.3 Resolution: | Keywords: newcomer 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 bgamari): We already have a [[http://downloads.haskell.org/~ghc/master/users-guide //using-optimisation.html?highlight=assert#ghc-flag--fignore-asserts|very similar]] mechanism for `Control.Exception.assert` occurrences at compile- time. It would be reasonably straightforward to add a similar flag for a magic synonym of `HasCallStack`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15559#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
