But the same is true for canvas creation arguments! $0 is not a creation
argument after all, i.e. it is not part of "ce_argv".
It was also never documented as an 'argument'. I understand there's an internal logical reason, but under a user perspective, we are never aware of it and really expect to be able to use it inside message boxes so they can communicate to local [receive] objects.
Another compelling reason is that Pd-L2ork and Purr Data allow this in their syntax and it would be beneficial to backport this to improve compatibility between patches.
Also, it really has a different purpose. So I don't really see the problem allowing it
in message boxes... $0 would be a special case either way.
We also have unexpected and weird behaviour in other places. It's all a matter of documenting. Actually, now that I am more explicitly documenting "$0" in Pd, it's all just way more complicated to document that you can't use "$0" in messages as you'd expect. So it's like we're documenting unexpected behaviour now instead of otherwise.
But I'll stop now :-)
