you need a new name for signed axis size?

int axis_size()

perhaps ;-)

both of you basically propose to have two similarly named "size" methods which return `unsigned` and `int` respectively. I really hope that you are kidding as indicated by the smileys in your messages.

Not really: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p1227r0.html

Ok, I see, thank you for the link. I am not sure if the proposal is the best solution for the show-case problem outlined in the proposal. My personal bias against having to similar "size" methods is high, since I feel that the high level interface now exposes a low-level problem, namely, how basic operators should work on signed and unsigned types.
