Description:
------------
Manual is a bit unclear about static methods. It doesn't imply that calling non-static methods in a static context (using the paamayim nekudotayim operator) is still valid.

Reproduce code:
---------------
<?php
class Foo {
    public function __construct() {
    }
    
    public function fromObject() {
        echo 'A call from the object <br/>';
    }   
    
    public static function fromStatic() {
        echo 'A static call <br/>';
    }
}

Foo::fromObject();
Foo::fromStatic();
?>
