Those would definitely be nice to have. I don't know what $@ refers to, is it the object arguments as a list?

However, it's worth understanding a bit about why Pd-l2ork has diverged somewhat from the code you'd be wrapping (in no particular order, and definitely not exhaustive):


That's all good info to know, thanks. I'd imagine libpd would't need to handle *move functions though. Does the dsp graph rely on positioning? I thought only via connections. I'd imagine the gui wrapper should only worry about positioning and simply update those changes when saving.
