Antony,
I don't at all disagree about the inappropriateness of this not triggering
an error but I did want to point out that this behavior is not consistent
with how __get() works. It seems like they should all behave similarly when
dealing with overriding methods or properties of different access levels.

mikel@mikel-desktop:~$ php -r 'class A { private $a; } $a = new A; $a->a;'
Fatal error: Cannot access private property A::$a in Command line code on
line 1

+++ Attempting to access a private property when __get() is defined
mikel@mikel-desktop:~$ php -r 'class A { private $a; public function
__get($var) { echo $var, "\n"; } } $a = new A; $a->a;'
a
