In Chrome 38, DOM collections have particularly buggy behavior with
respect to iteration—specifically, `Symbol.iterator in domCollection`
evaluates to `true`, but `domCollection[Symbol.iterator]` is undefined!
This bug is [mentioned in a `core-js` issue from around that
time](https://github.com/zloirock/core-js/issues/37#issuecomment-75811905).

Transpiled array destructuring uses iteration in its implementation, and
thus breaks when attempting to destructure a DOM collection in the
affected Chrome version(s). Because of the inconsistent feedback given
by the runtime, `core-js` isn’t able to effectively polyfill iteration
on this version.

So, just don’t destructure DOM collections—instead, do it the old
fashioned way.
