Let me rephrase that. I see now that it is designed that way, but I
think the logic is erroneous.  While I'm sure this argument/discussion
is all for naught now, I believe that a straight assignment of a value
to a variable, SHOULD NOT do any behind the scenes magic __set(). It
should just do it. Otherwise, what's the point of being able to "set" a
property/variable both ways? One gives no benefit over the other and as
illustrated decreases flexibility. It appears it will work if I change
my property to public, but I don't want them exposed like that. *sigh*

Bottom line is there should be a create_property($name, $value = null,
$type = 'protected') function/method that I can call to do what I'm
trying to do.

I assume unset($this->foo); works. So therefore, I can check for
existence of a property, and consequently remove a property, but I
cannot create a property.
