testing constexpr for calculation of compile time overflows.
...
Turns out that clang doesn't just overflow - it traps if there's an overflow - basically like safe<int> does at compile time.
Upshot is we have to trap overflows at compile time WITHOUT calculating them. In retrospect this is undefined behavior but no matter.
Next iteration will deal with this.
