Just to give another anecdote, I wrote myself a little tool last night
for visualizing healthcare scenarios to help my family decide which
insurance plan to choose this year.  I didn't realize until I added
'subTest's to the tests and mistakenly invoked them as "python -m
test" instead of "python3 -m test" that I'd accidentally written it to
be 2/3 compatible!  I took the subTest back out, and tests pass with
both interpreters.

(If such a tool could be useful to anyone, I can post it on
BitBucket/GitHub.  Its support for all possibilities is far from
complete, but it helped us a bit.  Also, I make no guarantees that you
won't want to gouge your eyes out reading the code, but that
*shouldn't* happen ;)
