@MattsJones Mind giving this a review?
I'm not sure how to get robust tests on this logic without having TypeScript as a dep and actually running it through the type-checker :/

TypeScript doesn't seem to like this. Here's a playground link that throws an error for this definition.

Huh that's interesting. Cheers.

We're running that exact version right now and I didn't see such an error come up when I manually tested this with *.d.ts files. I tweaked the playground to closer match what we do but it still gets errors.

This signals to me that merging this in would be a bad idea, though I don't understand why it's working with our build system. (Not that crazy, Webpack + ts-loader + TypeScript outputting ES5)

I'll close this for the time-being until I figure out a better solution.
