[issue26107] PEP 511: code.co_lnotab: use signed line number delta to support moving instructions in an optimizer

[Brett Cannon]

Brett Cannon added the comment:

There's technically no need to worry about ranged values as the magic number is purely an equality check to see if the interpreter matches what the .pyc was created with. I guess there might be third-party code that does a range check, but that's bad as importlib checks the raw bytes only; using a number is mostly a convenience for changing it.
