Originally I had as assert(0), but when I added the message, I realized that I needed to use `format`, which is not `nothrow`. Then `assumeWontThrow` will need to depend on itself in order for the catch clause to be `nothrow` (else the compiler will refuse this code).

On second thoughts, though, I could just wrap that around another try/catch, and die *really* horribly should `format`
