This is an absolute pain when dealing with strings that might be returned from autoescaped Twig as Twig_Markup objects. I'd warmly appreciate a bugfix even in 5.4...

The same issue.

Description:
------------
Per http://www.php.net/manual/en/language.types.array.php, array keys can be integers or strings.

If an object can be converted to a string representation (i.e. it has a __toString() method defined), it should be automatically cast to a string.  Currently, an error is thrown instead.

Current workaround is to manually cast to string when setting a key.

Test script:
---------------
class Foo {
    public function __toString() {
        return 'A';
    }
}

$a = new Foo();
$b = array($a => 1);

print_r($b);

Expected result:
----------------
Array
(
    'A' => 1
)

Actual result:
--------------
PHP Warning:  Illegal offset type [...]
Array
(
)
