#10744: Allow oneShot to work with unboxed types -------------------------------------+------------------------------------- Reporter: akio | 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 Revisions: -------------------------------------+------------------------------------- Comment (by nomeata): Hmm, I am not sure if this is a valid use of `oneShot` if you cannot guarantee that the Builder will be used only once, as GHC and the runtime (probably) relies on the annotation to be correct, and you might get crashes at runtime. If everything is inlined enough the existing arity analyses might be able to eta-expand `serialize`, but that’s probably not reliably enough. But nevertheless, the feature request is of course valid. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10744#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
