And it is good that you can't - as of PHP 5.4 the $this variable is
automatically bound, unless the closure is declared `static`. Adding a
possibility to alias $this could get really messy imho. With the
auto-binding the behavior is clear, but with the $this as $that syntax
several questions open up: a) Is $this the object as the public sees
it? I.e. the same as with the manual $that = $this assignment. Or does
it also expose private properties? b) If you use &$this as $that, will
$that automatically be rebound to the class it is used in?
