Isn't the display method involved as well?  I thought that was the 
method that was called to display an object, and that it might use disp 
internally?  And that Matlab's display method accepts a second argument 
to force the name tag that is used (Octave copies this feature since it 
appears to be required for basic compatibility even though it is not 
documented).

Anyway, I agree that compatibility is important for display and disp 
because they are used by classdef classes to display objects.  So if we 
aren't compatible, display of those objects won't work as expected.

I'm also just trying to understand what is required and how it is 
supposed to work.
