Description:
------------
When you have a type-hint error, the error message reports only the class the object should be, not the type it actually is:

Argument 1 must be an instance of Bar in hints.php on line 3

My experience so far indicates it would be tremendously helpful in debugging to know what class the object actually belongs to. As it is, I have to to *remove* the type hint and add a test inside the method to get that information. (I typically throw an exception to get a full stack trace.)


Reproduce code:
---------------
class Foo {
    public function process(Bar $bar) {}
}
class Bar {}
class Baz {}
$foo = new Foo;
$foo->process(new Baz);


Expected result:
----------------
Desired result:

Argument 1 is an instance of Baz, must be an instance of Bar in hints.php on line 3

Actual result:
--------------
Argument 1 must be an instance of Bar in hints.php on line 3
