An Input object is a container for data that the parallel\Events object will write to parallel\Channel objects as they become available. Multiple event loops may share an Input container - parallel does not verify the contents of the container when it is set as the input for a parallel\Events object.
Note:
When a parallel\Events object performs a write, the target is removed from the input object as if parallel\Events\Input::remove() were called.
