Hello,

I would like to start with an example:

    <?php

    class A {

         public static function foo ( ) {

             return 'foo';
         }
    }

    class B {

         protected $a = null;

         public function __construct ( ) {

             $this->a = new A();
         }

         public function a ( ) {

             return $this->a;
         }

         public function f ( ) {

             return $this->a::foo();
         }
    }

    $b = new B();
    var_dump($b->f());

This is not possible. We have a parse error in B::f because 
$this->a::foo() is not a construction of the language. But we can write:

    $a = $this->a; $a::foo();

In the same way, we can't write:

    $this->a()::foo();

I would like to know why? Is it a compiler related issue or just an 
omission? Would it be interesting to fix it?

Best regards.
