Proof: Get Iterate End State 60

Let's prove the following theorem:

if the following are true:

expression state at time 60 = "iterate_args"
arguments stack at time 60 = [ [ ], [ ] ]
parent stack at time 60 = [ self."x" = __add__(self.x, 5), [ ] ]

then expression state at time 61 = "call_function_begin"

Given

1	expression state at time 60 = "iterate_args"
2	arguments stack at time 60 = [ [ ], [ ] ]
3	parent stack at time 60 = [ self."x" = `__add__(self.x, 5)`, [ ] ]

Proof Table

#	Claim	Reason
1	expression state at time (60 + 1) = "call_function_begin"	if expression state at time 60 = "iterate_args" and arguments stack at time 60 = [ [ ], [ ] ] and parent stack at time 60 = [ self."x" = `__add__(self.x, 5)`, [ ] ], then expression state at time (60 + 1) = "call_function_begin" (Iterate Arguments Finished State Rule)
2	60 + 1 = 61	60 + 1 = 61 (Fixed Value Statement)
3	expression state at time (60 + 1) = expression state at time 61	if 60 + 1 = 61, then expression state at time (60 + 1) = expression state at time 61 (Substitution)
4	expression state at time 61 = "call_function_begin"	if expression state at time (60 + 1) = expression state at time 61 and expression state at time (60 + 1) = "call_function_begin", then expression state at time 61 = "call_function_begin" (Transitive Property of Equality Variation 2)
