I'm not sure I'd agree that it is hackish to set @instance_variables (or
perhaps to use a setter instead) to capture learned info.  A naming
convention might help (maybe remove the "?' and add "_reason")

class Foo
  attr_accessor :valid_reason
  def valid?
  ...
  self.valid_reason =3D "age is too young"
  false
  end
end
