Proof: Do Variables At Unchanged 78

Let's prove the following theorem:

if the following are true:
  • expression state at time 78 = "call_function_begin"
  • Variables Map at time 78 = [ entry self: (Python reference 0), [ ] ]

then Variables Map at time 79 = [ entry self: (Python reference 0), [ ] ]

Given
1 expression state at time 78 = "call_function_begin"
2 Variables Map at time 78 = [ entry self: (Python reference 0), [ ] ]
Proof Table
# Claim Reason
1 Variables Map at time (78 + 1) = Variables Map at time 78 if expression state at time 78 = "call_function_begin", then Variables Map at time (78 + 1) = Variables Map at time 78
2 Variables Map at time (78 + 1) = [ entry self: (Python reference 0), [ ] ] if Variables Map at time (78 + 1) = Variables Map at time 78 and Variables Map at time 78 = [ entry self: (Python reference 0), [ ] ], then Variables Map at time (78 + 1) = [ entry self: (Python reference 0), [ ] ]
3 78 + 1 = 79 78 + 1 = 79
4 Variables Map at time (78 + 1) = Variables Map at time 79 if 78 + 1 = 79, then Variables Map at time (78 + 1) = Variables Map at time 79
5 Variables Map at time 79 = [ entry self: (Python reference 0), [ ] ] if Variables Map at time (78 + 1) = Variables Map at time 79 and Variables Map at time (78 + 1) = [ entry self: (Python reference 0), [ ] ], then Variables Map at time 79 = [ entry self: (Python reference 0), [ ] ]
