This is most likely because default imports get wrapped in a `_interopDefault` function call by Babel. `common-shake` does not know what this function does (it could do anything) so it...

Some of Babel's module transform output may be tripping up common-shake. Could you share an example that shows it failing?

Thanks @retail-robot! `this` is really hard to make work correctly in all situations, but that particular case should not be too difficult to support.
