 Slightly off-topic, $this being equal to NULL reminds me of how ECMAScript 5
changed the value of "this" to "undefined" in strict mode when not being called
as a method. I agree it's a more sensible solution, as the disappearance of a
variable might be more difficult to deal with than a variable changing value.
With the latter, you can just do var_dump($this) and see it is now NULL, which I
expect would be less confusing than it suddenly not being present.
