No, I was just wondering if it would be a good use of our time to try to
use a scheme

Hi,
We were discussion integer promotion rules amongst the Numba team, and
we were wondering about the rationale for Numpy's rules. For example,
adding int8 and int8 will give int8 as result (with potential
magnitude loss), while adding int8 and uint8 will give int16 as result
(promoting to the
