Proof: Do Variables At Unchanged 58

Let's prove the following theorem:

if the following are true:
  • expression state at time 58 = "call_function_begin"
  • Variables Map at time 58 = [ entry self: (Python reference 0), [ ] ]

then Variables Map at time 59 = [ entry self: (Python reference 0), [ ] ]

Given
1 expression state at time 58 = "call_function_begin"
2 Variables Map at time 58 = [ entry self: (Python reference 0), [ ] ]
Proof Table
# Claim Reason
1 Variables Map at time (58 + 1) = Variables Map at time 58 if expression state at time 58 = "call_function_begin", then Variables Map at time (58 + 1) = Variables Map at time 58
2 Variables Map at time (58 + 1) = [ entry self: (Python reference 0), [ ] ] if Variables Map at time (58 + 1) = Variables Map at time 58 and Variables Map at time 58 = [ entry self: (Python reference 0), [ ] ], then Variables Map at time (58 + 1) = [ entry self: (Python reference 0), [ ] ]
3 58 + 1 = 59 58 + 1 = 59
4 Variables Map at time (58 + 1) = Variables Map at time 59 if 58 + 1 = 59, then Variables Map at time (58 + 1) = Variables Map at time 59
5 Variables Map at time 59 = [ entry self: (Python reference 0), [ ] ] if Variables Map at time (58 + 1) = Variables Map at time 59 and Variables Map at time (58 + 1) = [ entry self: (Python reference 0), [ ] ], then Variables Map at time 59 = [ entry self: (Python reference 0), [ ] ]
