1. readerC :: forall (m :: Type -> Type) r i o a . Monad m => (r -> ConduitT i o m a) -> ConduitT i o (ReaderT r m) a

   classy-prelude-conduit	ClassyPrelude.Conduit

   Wrap the base monad in ReaderT Since 1.0.11

2. readBoundedChan :: MonadConc m => BoundedChan m a -> m a

   concurrency	Control.Concurrent.Classy.BoundedChan

   Read an element from the channel. If the channel is empty, this routine will block until it is able to read. Blockers wait in a fair FIFO queue.

3. readCRef :: MonadConc m => CRef m a -> m a

   concurrency	Control.Concurrent.Classy.CRef

   Read the current value stored in a reference.

4. readChan :: MonadConc m => Chan m a -> m a

   concurrency	Control.Concurrent.Classy.Chan

   Read the next value from the Chan.

5. readIORef :: MonadConc m => IORef m a -> m a

   concurrency	Control.Concurrent.Classy.IORef

   Read the current value stored in a reference.

   readIORef ioref = readForCAS ioref >>= peekTicket
   

6. readMVar :: MonadConc m => MVar m a -> m a

   concurrency	Control.Concurrent.Classy.MVar

   Block until a value is present in the MVar, and then return it. This does not "remove" the value, multiple reads are possible.

7. readTBQueue :: MonadSTM stm => TBQueue stm a -> stm a

   concurrency	Control.Concurrent.Classy.STM.TBQueue

   Read the next value from the TBQueue.

8. readTChan :: MonadSTM stm => TChan stm a -> stm a

   concurrency	Control.Concurrent.Classy.STM.TChan

   Read the next value from the TChan.

9. readTMVar :: MonadSTM stm => TMVar stm a -> stm a

   concurrency	Control.Concurrent.Classy.STM.TMVar

   Read from a TMVar without emptying, or retry if it is empty.

10. readTQueue :: MonadSTM stm => TQueue stm a -> stm a

    concurrency	Control.Concurrent.Classy.STM.TQueue

    Read the next value from the TQueue.
