def get(property_name, inheritable_only=false)
  if inheritable_only || @this.nil?
    safe_instance_get("@#{property_name}")
  else
    value = @this.get(property_name)
    if value.nil?
      value = safe_instance_get("@#{property_name}")
    end
    value
  end
end

#set(property_name, value) ⇒ Object

if the property has a non-nil value set in the @this prop set, then we set it there. otherwise, it is set in the inheritable set.
