read :: MonadIO m => Ref a -> m a
reactive-banana Reactive.Banana.Prim.Low.Ref
readLatch :: Latch a -> Build a
reactive-banana Reactive.Banana.Prim.Mid
Read the value of a Latch at a particular moment in time.
buildLaterReadNow :: Build a -> Build a
reactive-banana Reactive.Banana.Prim.Mid
Pretend to return a value right now, but do not actually calculate it until later. NOTE: Accessing the value before it's written leads to an error. FIXME: Is there a way to have the value calculate on demand?
