this is not how send/receive work in Pd.
in general, Pd's messaging system works in a "push" manner, where data
is pushed from one object to the next, rather than a "pull" manner,
where an object requests a message from the previous one.

therefore, [receive] need not care which [send]s are attached to it.

then, [send] need not search for attached [receive]s either, because the
send-symbol will maintain a linked list of all attached receivers.
going through the linked list for dispatching a message is quite fast.
