The object on the call-site should remain to be an object (if it's not

It works in PHP-5 and PHP-7. Nothing should be changed.
$ sapi/cli/php -r 'class X {function __toString(){return "abc";}} $x=new
X; var_dump(strlen($x)); var_dump($x);'
int(3)
object(X)#1 (0) {
}
However, declare(strict_types=1) will break this. see

Thanks. Dmitry.
Dmitry, I was talking about passing an object to a function, expecting a
reference of a string:
'class X { function __toString() { return spl_object_hash($this); } } $x =
new X; function foo(string &$x){} foo($x); var_dump($x);'
Now what would this produce in Coercive STH is still an open question I
guess as there is no implementation yet.
