&gt; if a variable on the parent is changed, it would automatically be
&gt; inherited by all the clear variables, that is the ones that had the
&gt; same value as the old one.

I make a generic overhead lamp.  The default value for its `on'
variable is 0.  You make a child of my overhead lamp.  You turn it on.
You turn it off again.  I decide that the world needs more light, so I
set the default value to 1.  Your lamp goes on, inches from your face,
blinding you for several minutes.  (It's a bright lamp.)

Obviously there are ways to avoid this particular example.  Still, I
really don't like the assumption that because a child's value is equal
to the parent's value, the two are somehow linked.
