LGTM.

It would be nice to have a more generic solution, but I don't think there's a way to detect imports that is not fragile in some way.

[sentrivana]

Def not the most elegant of solutions, but should be good enough. We could probably also do this via importlib if we were fancy but it shouldn't be necessary.
