This allows the dynamic creation of an Inlet for a GraphStage which is
connected to a Sink that is available for materialization (e.g. using
the subFusingMaterializer). Care needs to be taken to cancel this Inlet
when the operator shuts down lest the corresponding Sink be left hanging.
This member is added by an implicit conversion from SubSinkInlet[T] to
any2stringadd[SubSinkInlet[T]] performed by method any2stringadd in scala.Predef.
