Currently we can imitate Arrays only with objects, where we would
refer to a value at some position via referring to objects property (
with integer index being converted to a string )
```js
var
Proxies should be enough for this. Is there any reason not to use them?

One advantage of this approach is that more spec magic can be implemented

versatile instead of having to always be a Proxy.

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)
6 matches
