Bug description:  "Internally overloading" null properties

Description:
------------
I was attempting to overload some object members when I came to the
realization that members defined as unaccessible from inside an object are
ones that have not been initialized at all. I was attempting to call a
defined but not yet set private member from a method in the class, I
expected the __get definition to execute and hopefully do a late member
cast but PHP saw it as accessible, this caused a problem because the method
was calling a NULL value.

The way I see it is that a NULL, aside from still being a value itself, is
pretty inaccessible as an actual value. My main concern is that calling an
undefined member returns NULL but is also defined as inaccessible, yet
calling a defined (but unset/not set) private/protected from within the
object, though returning null, is accessible.

In the end I know it's about scope and correctness, but is this issue up
for change?

Expected result:
----------------
Hello World!
Hello Universe!
Hello Everyone!

Actual result:
--------------
Hello World!

Hello Everyone!
