Hello, We are pleased to announce a new implementation draft of the StaticPointers extension [1]. We plan to improve the code still, and probably the interface of GHC.StaticPtr will undergo some changes, but the draft already covers the features that would make us happy to have in ghc 7.10. Looking forward to your comments. Best, Tweag I/O Team [1] https://phabricator.haskell.org/D550
