Proof: Get Iterate End Parent 77

Let's prove the following theorem:

if the following are true:
  • expression state at time 77 = "iterate_args"
  • arguments stack at time 77 = [ [ ], [ ] ]
  • parent stack at time 77 = [ self."y" = 5, [ ] ]

then parent stack at time 78 = [ ]

Given
1 expression state at time 77 = "iterate_args"
2 arguments stack at time 77 = [ [ ], [ ] ]
3 parent stack at time 77 = [ self."y" = 5, [ ] ]
Proof Table
# Claim Reason
1 parent stack at time (77 + 1) = [ ] if expression state at time 77 = "iterate_args" and arguments stack at time 77 = [ [ ], [ ] ] and parent stack at time 77 = [ self."y" = 5, [ ] ], then parent stack at time (77 + 1) = [ ]
2 77 + 1 = 78 77 + 1 = 78
3 parent stack at time (77 + 1) = parent stack at time 78 if 77 + 1 = 78, then parent stack at time (77 + 1) = parent stack at time 78
4 parent stack at time 78 = [ ] if parent stack at time (77 + 1) = parent stack at time 78 and parent stack at time (77 + 1) = [ ], then parent stack at time 78 = [ ]
