Travis CI job that just started failing today (10 Sep 2019) is here.

Jobs on <=3.7 are passing fine, so this might imply a change in Python behavior from 3.7->3.8? If so, not clear why the repo's py38 CI job passed ok.

Travis was using v3.8.0b4+, FWIW.

Full traceback:

This is a duplicate of #86. Let's take the discussion there.

Oops, sorry!

....ah, #86 was already closed, that's why I didn't see it.
