This thought as occurred to me, too, but examining it more carefully,
I came to the conclusion that casting has only to do with variables,
and not with objects. Runtime casting simply has no meaning, because
casting doesn't change the object, but only its type as known to the
compiler.
Indeed, since Q_EMIT is of type object in QObject, no casting is needed at all.
