Well, yea.

Wait a minute... could we set the methods we're interested in here to
protected instead of private?  And, as you suggest, just use the
singleton class?

  NoMethodError: protected method `attr_accessor' called for X:Class
          from (irb):11

Looks good!!! Not sure why this never occurred to me before. See
anything wrong with this approach?
