Proof: Get Iterate Expr 36

Let's prove the following theorem:

if the following are true:

expression state at time 36 = "iterate_args"
arguments stack at time 36 = [ [ last_name, [ ] ], [ ] ]

then the expression at time 37 = last_name

Given

1	expression state at time 36 = "iterate_args"
2	arguments stack at time 36 = [ [ last_name, [ ] ], [ ] ]

Proof Table

#	Claim	Reason
1	the expression at time (36 + 1) = last_name	if expression state at time 36 = "iterate_args" and arguments stack at time 36 = [ [ last_name, [ ] ], [ ] ], then the expression at time (36 + 1) = last_name (Iterate Arguments Expression Property)
2	36 + 1 = 37	36 + 1 = 37 (Fixed Value Statement)
3	the expression at time (36 + 1) = the expression at time 37	if 36 + 1 = 37, then the expression at time (36 + 1) = the expression at time 37 (Substitution)
4	the expression at time 37 = last_name	if the expression at time (36 + 1) = the expression at time 37 and the expression at time (36 + 1) = last_name, then the expression at time 37 = last_name (Transitive Property of Equality Variation 2)
