#14998: Sort out the strictness mess for exceptions -------------------------------------+------------------------------------- Reporter: simonpj | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.4.3 Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Exceptions 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 sgraf): Also shouldn't `catch#` at least be head-strict in its first argument? I'm pretty sure that would get rid of the bang pattern I had to introduce, while still having correct semantics: An `IO` action which throws ''when executed'' triggers the exception handler, while a call like `catch undefined h == undefined`, something I would expect. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14998#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
