#12620: Allow the user to prevent floating and CSE -------------------------------------+------------------------------------- Reporter: nomeata | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #9520, #8457 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by jpbernardy): edsko: the above definition would be rejected only if the **data** inside the conduit would be linear (`x`), instead of the conduit itself. It is fine to make the conduit type linear and its contents shared. Incidentally, I have written a stream library based on this idea, and it's described here: https://jyp.github.io/pdf/Organ.pdf The paper goes into the implication that linearity has in this case, in quite depth. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12620#comment:23 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
