I think the long thread here is more a reflection that it's an
interesting problem, and frankly, simple enough that almost anyone has
something to say about it.
But the fact that there is no one way to do it that is perfect for all
cases doesn't mean there isn't one way to do it that is useful in the
vast majority of cases.
I'm quite sure that most of the options on the table fit that bill, in fact.
And I'm optimistic that we can converge on an option that most
everyone on this thread can live with.

Sure -- but the idea is that you shouldn't have to. Particularly for
unittest.TestCase or quick command line checks.
