Proof: Get Iterate Params 7

Let's prove the following theorem:

if the following are true:

expression state at time 7 = "iterate_args"
arguments stack at time 7 = [ [ "Estonia", [ ] ], [ [ entry "MX": "Mexico", [ ] ], [ ] ] ]

then arguments stack at time 8 = [ [ ], [ [ entry "MX": "Mexico", [ ] ], [ ] ] ]

Given

1	expression state at time 7 = "iterate_args"
2	arguments stack at time 7 = [ [ "Estonia", [ ] ], [ [ entry "MX": "Mexico", [ ] ], [ ] ] ]

Proof Table

#	Claim	Reason
1	arguments stack at time (7 + 1) = [ [ ], [ [ entry "MX": "Mexico", [ ] ], [ ] ] ]	if expression state at time 7 = "iterate_args" and arguments stack at time 7 = [ [ "Estonia", [ ] ], [ [ entry "MX": "Mexico", [ ] ], [ ] ] ], then arguments stack at time (7 + 1) = [ [ ], [ [ entry "MX": "Mexico", [ ] ], [ ] ] ] (Iterate Arguments Pop Property)
2	7 + 1 = 8	7 + 1 = 8 (Fixed Value Statement)
3	arguments stack at time (7 + 1) = arguments stack at time 8	if 7 + 1 = 8, then arguments stack at time (7 + 1) = arguments stack at time 8 (Substitution)
4	arguments stack at time 8 = [ [ ], [ [ entry "MX": "Mexico", [ ] ], [ ] ] ]	if arguments stack at time (7 + 1) = arguments stack at time 8 and arguments stack at time (7 + 1) = [ [ ], [ [ entry "MX": "Mexico", [ ] ], [ ] ] ], then arguments stack at time 8 = [ [ ], [ [ entry "MX": "Mexico", [ ] ], [ ] ] ] (Transitive Property of Equality Variation 2)
