test_main.cpp is sort of an odd bird. It is unusual for a file sometimes
to be treated as a header, and other times as an implementation file. Thus
I'm still feeling my way as to what the best practice is for these
hermaphrodite files.

Interesting. I don't remember ever hearing any suggested practice for
ordering of #includes. Do you have a simple example of an error your
suggestion would detect? I think I understand your rationale, but an
