So, here's the deal of why I wanted to delete objects. My first idea was actually to create a dynamic number of outlets, but that didn't work, cause connections got lost. So I thought, well, maybe have a maximum number of outlets and delete them, but that turned out to be very much uglier than I thought and I haven't felt like trying yet.

But now I see there's this [initbang] external just for that... too bad that, like I said, I cannot afford to have an external dependency...  And then I've also seen there was a discussion of including [initbang] functionality in Pd Vanilla, which I believe it's of vital importance if we want Pd Vanilla to have any real functionality of providing powerful externals.
