An alternative that was discussed at one point was to invert this idea:
* Arrays get the methods that Maps already have: `get(index)` and `set(index,
value)`. Advantage: one could support negative indices. That is, the following
two expressions would be equivalent.
```js
arr.get(-1)
arr.get(arr.length-1)
```
* Using brackets for accessing array elements is phased out.
That may be easier to achieve and would fit in well with ES6 collections.
