What version of php are you using? It appears to work with RC1 to
CVS version. The actual result I get is:
public function Debug() {
echo self::$myInstance; // works
echo parent::$myInstance; // error: Cannot access protected property
echo A::$myInstance; // error: Cannot access protected property
}
Its expected for the errors on the last two since you're accessing
the protected variable from outsite the public scope of Debug().
