So, in order to avoid having the unit tests compiled into the code of anyone
who uses your template, you have to create a special version identifier that
you use with your unit test build and your documentation build, and then you
version the tests within the template with that version. And in order to
avoid having the unit test compiled into every instantiation of that
template during your test, you have to also put it in a static if for a
specific instantiation? Sure, that's feasible, but that's getting _ugly_.
