When you set up a test runner it all works just as intended, and has for a
decade or so (see below for a demo of timeDate by the late Diethelm Wuertz).
I feel rather strongly that this is in fact an area where we as a community
failed to elevate our best practices. But as the cheesy saying goes: "The
best time to plant a tree was 20 years ago. The second best time is now."
I agree with this.

Demo below runs off the _installed_ package which is a rather neat feature we
could stress more for more complete regression and rev.dep tests.
