Instead of trying to explaining my position, I threw together a quick PR to
illustrate my thoughts. Feel free to take another approach. I tested it with
`g++` configured, unconfigured, and not in my PATH on macOS, as well as on a
CentOS 7 with and without gcc installed, and an Ubuntu 14.04 box with an old
version of gcc installed (not C++11 compliant). All worked as expected.---
