#11035: Add implicit call-stacks to partial functions in base -------------------------------------+------------------------------------- Reporter: gridaphobe | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Resolution: | Keywords: 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 gridaphobe):
What if we add a special `rootCallStack :: CallStack` ...
I think this is doable. One thing worth stressing is that in your scenario the programmer has to '''explicitly''' say where they want the call-stack to be cut off (or to kill it altogether). This is in stark contrast to the existing scenarios, where call-stacks are handled entirely behind the scenes by GHC. But it sounds like you really want the option for explicit control, and I kinda understand why. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11035#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
