Description:
------------
Just see code ... $cl_foo is running correctly but $cl_bar not ...

It seems that there's two types of Closure ... same name ... different behavior ...

Actually I am not sure this is a bug or not ... get no clue reading the document ...

Test script:
---------------
<?php
$foo = new class {
    private $in = 'this is foo';
    
    public function func() {
        echo $this->cc;
    }
    
};

$bar = new class {
    private $in = 'this is bar';
};

$cl_foo = Closure::fromCallable([ $foo, 'func' ]);

$cl_bar = Closure::bind( $cl_foo, $bar );

Expected result:
----------------
this is bar // or "this is foo" ?

Actual result:
--------------
Cannot bind method class@anonymous::func() to object of class class@anonymous
