I've had a quick look at this PDF. Some random thoughts:

- The "safe integer" solution that I've heard most about is Miscrosoft's,
   which I don't think is one of those that you cite in your references.

- At the top of page 3 of your PDF there's an example where you square an
   int8_t and assign the result to an int8_t, and say this can't overflow.
   Either I'm missing something (which is quite possible!) or you meant to
   assign to a wider result type.

- I suspect that in my code, the consequences of an exception that I
   hadn't considered could be just as bad as an overflow that I'd not

Regards, Phil.
