Description:
additional types of channels for STM; profiling libraries
Additional types of STM channels: * TBChan: a version of TChan where the queue is bounded in length * TBMChan: a version of TChan where the queue is bounded in length and closeable. * TBMQueue: a version of TQueue where the queue is bounded in length and closeable. * TMChan: a version of TChan where the queue is closeable. This is similar to a TChan (Maybe a) with a monotonicity guarantee that once there's a Nothing there will always be Nothing. * TMQueue: a version of TQueue where the queue is closeable. This is similar to a TQueue (Maybe a) with a monotonicity guarantee that once there's a Nothing there will always be Nothing. . This package provides a library for the Haskell programming language, compiled for profiling. See http://www.haskell.org/ for more information on Haskell.
