Expected Behaviour

In the linked repl, I would expect the options array to retain the car property (because it's called by another function). And treeshake the unused bar property.

Actual Behaviour

The car property is removed, which would break the car() call. The bar property is retained, even though it is never used.

Note that this nearly equivalent repl behaves as expected. The only difference is that it destructures properties within the function body.
