This looks like a serious regression in 3.7.  @ned.deily - I'm marking this as a release blocker, but feel free of course to downgrade it.

Run the following as

$ python3.6 badconfig.py
Hey, it works!

$ python3.7 badconfig.py
Traceback (most recent call last):

I'm still investigating, but wanted to get the bug filed asap.
