Now we're talkin'
I think some sort of efficiently implemented tree would be a great idea.  
The issue is that there are a few levels of data to hack trough. Grob  
arrays contain grove, which have properties, which themselves may be Grob  
arrays. So, one still needs to pass through the property or object lookup  
mechanism. If there is a way to implement a tree data structure while  
preserving the core Grob/property model, I'm all for it.
