I think you missed what I said.
Consider the following example:
function foo($obj)
{
         $obj->bar;
}

You have no idea what type (and/or class type) $obj is at compile-time.
So you can't know if $obj's bar property is private or not.
However, if you'd have the following syntax:
function foo(class MyObject $obj)
{
         $obj->bar;
}
You could know at compile time if the MyObject class's bar member was
defined as private.
