Subject<void> and next() optional value

[artaommahe]

Can we make Subject's next() method value optional? It's usefull for some use cases then u just need to trigger some action without any data providing to it

this.smthSubject = new Subject<void>();
...
this.smthSubject.next();

currently it will fall with error

Error TS2346: Supplied parameters do not match any signature of call target.

My current usecase is to trigger ng1(2) directive action. Directive is scrollbar wrapper and i need to trigger scrollbar update on some parent element events. I used $scope.$broadcast() for this with ng1, but currently i write ng1 code in TS with ng-metadata for further upgrading to ng2 and in search for this use case implementation without scope pubsub.

Yes, we should do this.
