@RWOverdijk the fact that you are not a minority does make that comment moot :D

Where i work, we all have this in our shell startups:

alias fuckit="sudo"
alias I_quit="rm -fr /"

Then, one day, when it's all too much you can just do

$ fuckit I_quit

and start walking....

Version number ?
Release date ?

maybe a Conference about it?

You need to add --no-preserve-root

This version won't even let you assign it to a variable (made it really fast and it's just a joke):

<?php

class Untouchable {
    private static $count;
    private static $register = [];
    private $id;

    public static function create()
    {
        return new self(self::$count++);
    }
    public static function check()
    {
        echo 'Checking...'.PHP_EOL;
        if (count(self::$register)) {
            throw new Exception('Can\'t touch this');
        }
    }
    private function __construct($id)
    {
        $this->id = $id;
        self::$register[$this->id] = true;
    }
    public function __destruct()
    {
        echo 'I was destroyed: '.$this->id.PHP_EOL;
        unset(self::$register[$this->id]);
    }
}

declare(ticks=1);
register_tick_function([Untouchable::class, 'check']);

function foo(): Untouchable {
    return Untouchable::create();
}

foo();
$a = foo(); // Cant touch this
echo 'end of script'.PHP_EOL;

@jp7carlos that is AWESOME!

You have code duplication on lines 16 and 21. I honestly expected better.

This just made my day!
