Proof: Get New State 21

Let's prove the following theorem:

if expression state at time 21 = "return", then expression state at time 22 = "iterate_args"

Given

1	expression state at time 21 = "return"

Proof Table

#	Claim	Reason
1	expression state at time (21 + 1) = "iterate_args"	if expression state at time 21 = "return", then expression state at time (21 + 1) = "iterate_args" (Return State Property)
2	21 + 1 = 22	21 + 1 = 22 (Fixed Value Statement)
3	expression state at time (21 + 1) = expression state at time 22	if 21 + 1 = 22, then expression state at time (21 + 1) = expression state at time 22 (Substitution)
4	expression state at time 22 = "iterate_args"	if expression state at time (21 + 1) = expression state at time 22 and expression state at time (21 + 1) = "iterate_args", then expression state at time 22 = "iterate_args" (Transitive Property of Equality Variation 2)
