I have no idea how to parse your comment or how it relates to what I said.

All I said is that you can remove undefined behavior from signed overflow without having to introduce checks to every arithmetic operation and without having to specify any particular behavior or outcome. The technical term for this is "unspecified behavior" and the consequence of making overflow unspecified behavior is that the consequences of overflow, while still unspecified, must be bounded in space and time, unlike undefined behavior whose consequences are not required to be bounded in either space or time.
