And you still have the problem that all of those unit tests will be compiled
into every instantiation of the template that's part of your unittest build.
So, you end up with longer build times and longer run times for your unit
tests. I agree that copy-pasting sucks, but it's what we had to do before
with had ddoc-ed unit tests, and I still think that it's better than
resulting in all of the additional copies of the tests being compiled in and
run - especially if the project isn't small.
