data TChan a
`TChan` is an abstract type representing an unbounded FIFO channel.
newTChan :: STM (TChan a)
readTChan :: TChan a -> STM a
writeTChan :: TChan a -> a -> STM ()
dupTChan :: TChan a -> STM (TChan a)
unGetTChan :: TChan a -> a -> STM ()
isEmptyTChan :: TChan a -> STM Bool
Returns `True` if the supplied `TChan` is empty.
