NAME

       "Event::Distributor::Signal" - an event that returns no result

DESCRIPTION

       This subclass of Event::Distributor::_Event invokes each of its subscribers in turn,
       ensuring each has a chance to be invoked regardless of the result of the others.

       Its Future succeeds (with no value) if no subscriber failed. If one subscriber failed, the
       "Future" fails in the same way. If two or more subscribers fail, the resulting "Future"
       fails with a message composed by combining all the individual messages, in the
       "distributor" category, whose failure details are a list of the failed component futures.
