OK, thanks. This is the information I was after. Ie. I should not assume 
that, though it might be kind of cool if there was a way to do what I was 
thinking.

Then I actually gain very little compared to doing it inside namespaces. 
It would've helped for the methods to know their context and also for 
variables to be used (my first version did all this work manually). I can 
still get that with directly manipulating Tcl namespaces, I think, but 
it's just a tad more awkward than what I thought I'd get with XOTcl 
objects (because I also have to create structures and objects for my 
parser -- using namespaces instead of XOTcl obs).
