if the following are true:

• Expression Stack at time t = [ [ ], [ [ Python constructor with name: class_name and arguments: args, ys ], rest ] ]
• Function Variables Map at time t = [ ]
• Parameters List at time t = [ self, p_rest ]

then Function Variables Map at time (t + 1) = [ entry self: (Python reference (length of stack (Python Object Store at time t))), [ ] ]
