Sorry, I mustn't have communicated it well enough. I wanted the tests to ensure that any .d.ts file does not export an @types interface accidentally. This PR isn't necessary, what's really needed is something that'll go over all the dependencies and @types to find the types referenced in generated .d.ts files to ensure that any imports aren't used accidentally. Does that make more sense? For example:

import * as Foo from 'foo'

export const x: Foo.Bar = { ... }

In the above example Foo.Bar is a type, maybe coming from @types/foo, and it has been exported as part of the package. For a TypeScript user to use this file, @types/foo must be a dependency.

I see. It seems reasonable, but testing is not so easy. Considering.
