Proof: Get Iterate End Expr 8

Let's prove the following theorem:

if the following are true:

expression state at time 8 = "iterate_args"
arguments stack at time 8 = [ [ ], [ ] ]
parent stack at time 8 = [ __eq__(1, 3), [ ] ]

then the expression at time 9 = __eq__(1, 3)

Proof:

Given

1	expression state at time 8 = "iterate_args"
2	arguments stack at time 8 = [ [ ], [ ] ]
3	parent stack at time 8 = [ `__eq__(1, 3)`, [ ] ]

Proof Table

#	Claim	Reason
1	the expression at time (8 + 1) = `__eq__(1, 3)`	if expression state at time 8 = "iterate_args" and arguments stack at time 8 = [ [ ], [ ] ] and parent stack at time 8 = [ `__eq__(1, 3)`, [ ] ], then the expression at time (8 + 1) = `__eq__(1, 3)` (Iterate Arguments Finished Rule)
2	8 + 1 = 9	8 + 1 = 9 (Fixed Value Statement)
3	the expression at time (8 + 1) = the expression at time 9	if 8 + 1 = 9, then the expression at time (8 + 1) = the expression at time 9 (Substitution)
4	the expression at time 9 = `__eq__(1, 3)`	if the expression at time (8 + 1) = the expression at time 9 and the expression at time (8 + 1) = `__eq__(1, 3)`, then the expression at time 9 = `__eq__(1, 3)` (Transitive Property of Equality Variation 2)
