Proof: Get Iterate End Parent 38

Let's prove the following theorem:

if the following are true:

expression state at time 38 = "iterate_args"
arguments stack at time 38 = [ [ ], [ ] ]
parent stack at time 38 = [ joe.move(), [ ] ]

then parent stack at time 39 = [ ]

Given

1	expression state at time 38 = "iterate_args"
2	arguments stack at time 38 = [ [ ], [ ] ]
3	parent stack at time 38 = [ `joe.move()`, [ ] ]

Proof Table

#	Claim	Reason
1	parent stack at time (38 + 1) = [ ]	if expression state at time 38 = "iterate_args" and arguments stack at time 38 = [ [ ], [ ] ] and parent stack at time 38 = [ `joe.move()`, [ ] ], then parent stack at time (38 + 1) = [ ] (Iterate Args Empty (3))
2	38 + 1 = 39	38 + 1 = 39 (Fixed Value Statement)
3	parent stack at time (38 + 1) = parent stack at time 39	if 38 + 1 = 39, then parent stack at time (38 + 1) = parent stack at time 39 (Substitution)
4	parent stack at time 39 = [ ]	if parent stack at time (38 + 1) = parent stack at time 39 and parent stack at time (38 + 1) = [ ], then parent stack at time 39 = [ ] (Transitive Property of Equality Variation 2)
