This is something I did not know about Max. I presume that is only with
signal objects as I don't recall seeing that with non-signal ones? Perhaps
this would be an opportunity to revisit nlet code to make it more
versatile? I have on pd-l2ork's TODO to explore implementing nlets that can
split signal and non signal, as well as refuse to connect things that
shouldn't be connected, which works only in some cases. Perhaps this calls
to also report when something is connected into the nlet?
