trigger(num v) → void: Following certain practices on Rx data, we might want to react to certain listeners when a value has been provided, even if the value is the same. At the moment, we ignore part of the process if we .call(value) with the same value since it holds the value and there's no real need triggering the entire process for the same value inside, but there are other situations where we might be interested in triggering this.
