Anyone have ideas on more examples? It’s tempting to make a transpiler
plugin to see how it works in practice, but I’d like to see more examples
first. Thanks

Maybe it would be less footgunny to support autovivification in a more
class-based way, like Python does?
```javascript
class AutoVivArray extends Array {
[Symbol.getMissing](identifier) {
/* if we're here, identifier is not an ownProperty
* and is nowhere on the prototype chain */
Is the Perl syntax opt-in like the proposed operator? Or does it happen on
all accesses to nulls? If it's opt-in in JS, then it doesn't seem to me
that it'd cause too much unexpected behavior, though it could be argued
that it's ripe for abuse by new devs trying to avoid errors.
