Yes, I can have functions/methods that do math differently from the default. I could just as easily say that's C's way and mix and match those: int64_t x

Yes, I can have functions/methods that do math differently from the default. I could just as easily say that's C's way and mix and match those: int64_t x = add_i64_with_abort_on_debug_and_wrap_on_release(y, z); uint8_t t = add_u8_with_saturation(u, v); I'd prefer the default for the math operators be what all the CPUs currently do, and neither C or Rust promises that.
