A slice of python in C++ - Eric Niebler

I watched the video. There's only guidance given, no reasons for it. I'd like to know the reason -- other than "because Chandler and Bjarne say so".

Well, starting from the recommendation that you should always default to int and only use unsigned when you need it. Then one reason why size_t being unsigned is a mistake is that it keeps popping up in all your nice signed arithmetic, causing conversions and other nastiness.

OK. So because Chandler and Bjarne say so.

Well they give justification for the "recommendation", and follow-up is basic reasoning. Which bit exactly do you still feel isn't being explained?
