This is probably my biggest stylistic gripe with PHP 8+ just because of how
ubiquitous the "undefined array index" scenario is.
In JavaScript:
```
let obj = {};
obj['undefinedkey'] === undefined;
let str =
Welcome, ${obj['undefinedkey'] ?? 'Customer'}!;
if( obj['undefinedkey'] || $obj['undefinedkey2'] ) doSomething();
```
In PHP:
```
$obj = [];
($obj['undefinedkey'] ?? null) === null;
$str = "Welcome, " . ($obj['undefinedkey'] ?? 'Customer') .
"!";
if( ( $obj['undefinedkey'] ?? null) || ($obj['undefinedkey2'] ?? null) )
doSomething();
```
