There’s also Rust’s half-measure of overflow in release mode, panic in debug mode.

It takes two lines in your Cargo.toml to turn overflows into panics in release mode in rust, if you don't mind the performance hit.

Or more sensibly you can set clippy lints to disallow any operation that may overflow, forcing you to specify the desired behavior (either with the .{wrapping,checking,saturating}_{sub,add,mul,div} functions or the Saturating<Type> etc wrappers)

Okay thanks.

Similarly, with C#, you can compile with exception-on-overflow for integers. This is all great, but this should really be the default behavior for basic arithmetic operators, even in release builds. For cases where you want overflow (or saturation, or UB) there should really be distinct operators. Maybe something like <+> for wraparound, [+] for saturation etc.
