Subject: [PATCH] Reverting 741da7806c5d01796e243de9a122590151cb0c90, which was
 causing issues due to loose type checking

See this example on why the revert is needed: https://3v4l.org/8T34v

Code copied for reference:

```php
<?php

$a = 1;

switch ($a) {
    case "1";
        echo "FUCK YOU, STUPID LANGUAGE!";
        break;
    case 1;
        echo __LINE__;
        break;
}
```
