Lifted and unlifted classes and functions for the STM monad. To get started, just:

import Control.Concurrent.STM.Unlift

This is meant to be a drop-in replacement for Control.Concurrent.STM.

This package provides functionality for the STM monad, which is highly analagous to the functionalty for the IO monad found in Control.Monad.IO.Class, Control.Monad.IO.Unlift, and UnliftIO.STM:

• MonadSTM is a copy of MonadIO modified for STM
• MonadUnliftSTM is a copy of MonadUnliftIO modified for STM
• Some functions found in Control.Concurrent.STM.Unlift are re-exported directly from UnliftIO.STM
