signed_size

A header only utility function for getting the size of a container as a signed type.

Motivation

In a nutshell: It allows to use old-style for loops without triggering sign comparison warnings:

    for (int i = 0; i < signed_size(container); ++i) { ... }
    for (int64_t i = 0; i < signed_size(big_container); ++i) { ... }
