This bug was fixed in #28528 and then reverted in #28675 because it broke a common pattern in Redux type exports, as documented in #28620. However, it still seems correct (at least, technically correct) that a reference to x in typeof x shouldn't count as a use.

That looks like a use to me, even if it's only a type-only use.

The only other way you have to use it is with typeof import('something').x.
