Proof step 25 from proof fix2rest-last (previous step)

1 = # bytes0, 0 ≤ bytes2int(by ' + bytes0) ⊦ bytes0 = [], bytes0 = (by ' + bytes0).last '

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 26:
1 = # bytes0, 0 ≤ bytes2int(by ' + bytes0) ⊦ bytes0 = [], bytes0 = bytes0.last '

Rule argument

Additional information

Used simplifier rules: ⊦ (bytes + bytes0) + bytes1 = bytes + bytes0 + bytes1;% ⊦ bytes ≠ [] → (by ' + bytes).last = bytes.last;
