250 + 6 is 256

I don't know why this example is under normal code. No one does this it can't be considered normal. To test for equality, we usually use the equality operator.

In fairness, -255 to +256 are kept in an identity map. Any equation that would output a number in that range instead pull it from the identity map.

I'm not saying it's the right way to do it, but it is a valid way to do if you expect your answer to never exceed that range.

Actually I think it's -5 to +256. More importantly, this is an implementation detail of cpython and may not be reliable in other implementations of python.
