I recall on the projects page that one of the ideas was that the builtins 
may work better as part of a structure.  If we were to go with this 
toolbox idea, then it would make sense to me that the variables for the 
toolboxes would go into that structure like:

octave_builtins.<toolboxname>.<toolboxvar>

This could have the benefit that the octave_builtins variable would be 
always global and so all of the toolbox variables would be global by 
default (I think that I read what the problems were).  Hopefully this 
makes sense because I'm not sure that I have correctly followed this 
thread.
