Description:
------------
$this is available inside a statically called mehod when it is called from inside an object not an instance of this class

Reproduce code:
---------------
<?php
class Foo {
    function foo() {
        if ( isset( $this ) ) {
            return '$this available';
        } else {
            return '$this NOT available';
        }
    }
}
class Bar {
    function callFoo() {
        echo 'Foo::foo(): ' . Foo::foo() . "\n";
    }
}

$foo = new Bar();
$foo->callFoo();
?>

Expected result:
----------------
Foo::foo(): $this NOT available

Actual result:
--------------
Foo::foo(): $this available

$this should not be available inside a method called with the scope-resolution-operator if the call comes from an object not beeing an instance of the same class as the called method

i read both. and the doc more than once

the scope resolution operator is to call methods from a parent class, and there should $this available.

but why is $this available when the method is not of a parent class?

btw. doesnt it pollutes the lokal namespace?
