That's what I would expect, but why does the snippet work? $this gets
generated on the fly by some magic I don't understand.

class foo {

  var $bar = 0;

  function do() {

    var_dump($this);
    $this->bar = 3;
    var_dump($this);

    print $this->bar;

  }
}
foo::do();

If "::" introduces static calls what's the syntax to access properties
and methods of foo from within do() ? Of course this can't be done using
the pseudo object $this .
