Description:
------------
self seems te be a string until a method is called on it.

this makes it impossible to get any information about self at all.

Reproduce code:
---------------
<?php
class Heh {
 
    static function hi() {
        echo "Type of self is: ".gettype(self)."\n";
        var_dump(self);
        echo "Calling method huh, on self which is a string!?\n";
        self::huh();
    }
 
    static function huh() {
        echo "huh?\n";
    }
 
}
 
Heh::hi();

Expected result:
----------------
self is anything but a string.

Actual result:
--------------
Type of self is: string
string(4) "self"
Calling method huh, on self which is a string!?
huh?
