* Remove name parameter (no overloads), naming is performed using `.withAttributes` or the new convenience `.named`. Those adds the OperationAttribute.Name and also change the name of the shape Inlet and Outlet. * Remove Source/Sink parameter list for 0 parameter methods, this allows usage of `Sink.head` instead of `Sink.head()`
