Let's say I have foo_class that creates object [foo] and bar_class which creates object [bar].

I want the inlet of both to forward incoming messages to an object of type blah_class which serves as a proxy inlet.  (The struct of foo and bar would store a pointer to it and control creation and freeing of it.)

Is there a way to specify this inside foo_new and bar_new, or is the easiest way to just use a class_addanything and forward messages that way?
