#7991: stm: add mkWeakTVar --------------------------------------+------------------------------------ Reporter: errge | Owner: simonmar Type: feature request | Status: patch Priority: highest | Milestone: 7.8.1 Component: libraries (other) | Version: 7.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: --------------------------------------+------------------------------------ Comment (by errge): Sorry, I broke the link in the description by deleting the pull request repository. Here is an updated link: https://github.com/Gabriel439/Haskell-Pipes-Concurrency- Library/blob/master/src/Pipes/Concurrent.hs#L211 The only reason why Tekmo is doing unsafeIOToSTM here is because there is no mkWeakTVar. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7991#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
