@rayman22201, thanks, that got me over that hump and much further along.
Now I'm running into cases where obj.proc (in my case, node.left for example) doesn't seem to work for method functions (in my case left) when there are arguments to the enclosing function with the same name as the method (in my case left). It worked before when left was a field of the object. I suspect I have hundreds of these to fix in my code... I'll report back when I've made all those changes to the argument names.
