Proof: Get Iterate State 13

Let's prove the following theorem:

if the following are true:

expression state at time 13 = "iterate_args"
arguments stack at time 13 = [ [ "Smith", [ 25, [ ] ] ], [ ] ]

then expression state at time 14 = "begin_expr"

Given

1	expression state at time 13 = "iterate_args"
2	arguments stack at time 13 = [ [ "Smith", [ 25, [ ] ] ], [ ] ]

Proof Table

#	Claim	Reason
1	expression state at time (13 + 1) = "begin_expr"	if expression state at time 13 = "iterate_args" and arguments stack at time 13 = [ [ "Smith", [ 25, [ ] ] ], [ ] ], then expression state at time (13 + 1) = "begin_expr" (Iterate Arguments State Property)
2	13 + 1 = 14	13 + 1 = 14 (Fixed Value Statement)
3	expression state at time (13 + 1) = expression state at time 14	if 13 + 1 = 14, then expression state at time (13 + 1) = expression state at time 14 (Substitution)
4	expression state at time 14 = "begin_expr"	if expression state at time (13 + 1) = expression state at time 14 and expression state at time (13 + 1) = "begin_expr", then expression state at time 14 = "begin_expr" (Transitive Property of Equality Variation 2)
