Overnight I had the following thought, which I think could work rather well. The most basic implementation of the idea is as follows:
class MonadST s m | m -> s where liftST :: ST s a -> m a
instance MonadST s (ST s) where ... instance MonadST s m => MonadST ...
Like MonadIO, isn't it?
I think it should be, except that you need to track 's' somewhere.
