Somewhat ironically, one could say that typed scalar variables are 
already supported,
albeit with a somewhat cumbersome syntax.

Instead of

  ```php

int $intVar;

```
you write

```php
class TypedInt {
     public static int $intVar = 0;
}
$intVar = &TypedInt::$intVar;

echo $intVar; // 0

$intVar = 3;
echo $intVar; // 3

$intVar = 'x'; // Fatal error: Uncaught TypeError
```
