On regular PHP 7, the array weirdness (Dmitry's last example) doesn't even
produce a warning:

class Shit {
    public $yo = false;
}

$shit = new Shit();

$shit->yo[] = "what"; // quitly turns $yo into an array!

echo gettype($shit->yo); // array

That's pretty messed-up right there. At least in the object cases there's
an E_WARNING "Creating default object from empty value" - with the array
case, nothing, it just converts your boolean into an array. Yiiiiikes.
