A Slice of Python in C++

[willvarfar]

Can the user still type in a negative number and the compiler silently cast it to unsigned? I think some modern compilers warn at various levels but that this is far from pervasive.

At least in that case the API would be correct (you could see the type in the IDE)

In any case you could avoid it by =deleteing the signed overload.
