Proof: Get Iterate End State 57

Let's prove the following theorem:

if the following are true:

expression state at time 57 = "iterate_args"
arguments stack at time 57 = [ [ ], [ [ ], [ ] ] ]
parent stack at time 57 = [ __add__(self.x, 5), [ self."x" = __add__(self.x, 5), [ ] ] ]

then expression state at time 58 = "call_function_begin"

Given

1	expression state at time 57 = "iterate_args"
2	arguments stack at time 57 = [ [ ], [ [ ], [ ] ] ]
3	parent stack at time 57 = [ `__add__(self.x, 5)`, [ self."x" = `__add__(self.x, 5)`, [ ] ] ]

Proof Table

#	Claim	Reason
1	expression state at time (57 + 1) = "call_function_begin"	if expression state at time 57 = "iterate_args" and arguments stack at time 57 = [ [ ], [ [ ], [ ] ] ] and parent stack at time 57 = [ `__add__(self.x, 5)`, [ self."x" = `__add__(self.x, 5)`, [ ] ] ], then expression state at time (57 + 1) = "call_function_begin" (Iterate Arguments Finished State Rule)
2	57 + 1 = 58	57 + 1 = 58 (Fixed Value Statement)
3	expression state at time (57 + 1) = expression state at time 58	if 57 + 1 = 58, then expression state at time (57 + 1) = expression state at time 58 (Substitution)
4	expression state at time 58 = "call_function_begin"	if expression state at time (57 + 1) = expression state at time 58 and expression state at time (57 + 1) = "call_function_begin", then expression state at time 58 = "call_function_begin" (Transitive Property of Equality Variation 2)
