This. I think the original implementers had a different idea of 
how things would be used. For a long time, unittests would run 
first, then the main would be called. We all know how annoying 
that was, (most) people do not want this, they wanted two 
different modes, clearly separated. I say most, because there are 
still a few hold out I think.

Personally, I'd like my unittest binary to generate something 
that has a much better UX than what's currently in druntime. You 
know, timing statistics, colors, ability to run a single test, 
the whole thing.

I'm aware that there are frameworks out there, but it needs to be 
built-in.
