 There are some new objects with `toLocaleString()` (`TypedArray`
 (https://developer.mozilla.org/en-
 US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray/toLocaleString),
 `Array` (https://developer.mozilla.org/en-
 US/docs/Web/JavaScript/Reference/Global_Objects/Array/toLocaleString))
 which should according to the docs use all the same algorithm as the one
 in `Number`.

 We should make sure that no locale is leaked and probably write a test for
 that.
