I don't mean that it's just a user-wise thing and thus not an 
implementation thing. I mean that it's a user-wise thing 
therefore you don't have the choice to imitate it using a special 
implementation, if you are going to imitate it faithfully.

The $-substitution isn't run on messageboxes when they get instantiated. 
That's the difference I'm talking about. This is also the difference that 
the new messagebox wouldn't imitate, so the new-style messageboxes 
wouldn't need weird hacks in the pd source; but if anyone wanted to 
reimplement old-style messageboxes, they'd need to find a way to disable 
$-substitution in that case.
