Proof: Get Iterate End State 72

Let's prove the following theorem:

if the following are true:

expression state at time 72 = "iterate_args"
arguments stack at time 72 = [ [ ], [ ] ]
parent stack at time 72 = [ __mul__(self.age, 12), [ ] ]

then expression state at time 73 = "call_function_begin"

Given

1	expression state at time 72 = "iterate_args"
2	arguments stack at time 72 = [ [ ], [ ] ]
3	parent stack at time 72 = [ `__mul__(self.age, 12)`, [ ] ]

Proof Table

#	Claim	Reason
1	expression state at time (72 + 1) = "call_function_begin"	if expression state at time 72 = "iterate_args" and arguments stack at time 72 = [ [ ], [ ] ] and parent stack at time 72 = [ `__mul__(self.age, 12)`, [ ] ], then expression state at time (72 + 1) = "call_function_begin" (Iterate Arguments Finished State Rule)
2	72 + 1 = 73	72 + 1 = 73 (Fixed Value Statement)
3	expression state at time (72 + 1) = expression state at time 73	if 72 + 1 = 73, then expression state at time (72 + 1) = expression state at time 73 (Substitution)
4	expression state at time 73 = "call_function_begin"	if expression state at time (72 + 1) = expression state at time 73 and expression state at time (72 + 1) = "call_function_begin", then expression state at time 73 = "call_function_begin" (Transitive Property of Equality Variation 2)
