Proof step 15 from proof fix2rest-last (previous step)

2 ≤ # bytes ⊦ ¬ bytes2int(bytes) < 0, lastn(2, bytes).rest = bytes.last ', bytes = [], ¬ 2 < # bytes ∧ ¬ 0 ≤ bytes2int(bytes)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 16:
2 < # bytes, bytes2int(bytes) < 0 ⊦ lastn(2, bytes).rest = bytes.last ', bytes = []

Rule argument

Additional information

Used simplifier rules: ⊦ j < i ∧ i ≤ 0 → j < 0; (forward)% ⊦ m < n → m ≤ n;% ⊦ i < j → (¬ ¬ j ≤ i ↔ false);
