[Grammatica-users] Grammar for "Nesting"

[Patrick M Gremo]

I'm trying to create a kind of "reverse" call stack type of thing.  It
sounds easy but for some reason I just can't figure it out.

I have this:

(object | methodCall) methodCall methodCall methodCall ...


I want a tree like:

message
   |-methodCall
   |-message
        |-methodCall
        |-message
             |-methodCall
             |-message
                  |-object | methodCall
