Documentation
The applicative instance of this combines multiple Producers reactively ie, yields a value as soon as either or both of the input producers yields a value.
Impulse  

Monad m => Functor (Impulse m) Source #  
(Alternative m, Monad m) => Applicative (Impulse m) Source #  Impulseively combines two producers, given initial values to use when the producer is blocked/failed.
This only works for Alternative m where failure means there was no effects, eg. 
(Alternative m, Monad m) => Merge (Impulse m) Source #  Impulseively combines two producers, given initial values to use when the produce hasn't produced anything yet
Combine two signals, and returns a signal that emits
