Proof: Get Iterate Expr 28

Let's prove the following theorem:

if the following are true:

expression state at time 28 = "iterate_args"
arguments stack at time 28 = [ [ first_name, [ ] ], [ ] ]

then the expression at time 29 = first_name

Given

1	expression state at time 28 = "iterate_args"
2	arguments stack at time 28 = [ [ first_name, [ ] ], [ ] ]

Proof Table

#	Claim	Reason
1	the expression at time (28 + 1) = first_name	if expression state at time 28 = "iterate_args" and arguments stack at time 28 = [ [ first_name, [ ] ], [ ] ], then the expression at time (28 + 1) = first_name (Iterate Arguments Expression Property)
2	28 + 1 = 29	28 + 1 = 29 (Fixed Value Statement)
3	the expression at time (28 + 1) = the expression at time 29	if 28 + 1 = 29, then the expression at time (28 + 1) = the expression at time 29 (Substitution)
4	the expression at time 29 = first_name	if the expression at time (28 + 1) = the expression at time 29 and the expression at time (28 + 1) = first_name, then the expression at time 29 = first_name (Transitive Property of Equality Variation 2)
