In this case, isValid_ should be protected and derived classes would =
have to manage it.=20

I agree with you, we could also leave it as it is and provide a =
protected function setQuote() which would set isValid_ to true.

I agree again, provided that you add a resetQuote() method to your =
class, then the use of optional would be transparent to the user. Still, =
I have two remaining arguments:=20
->You have to reimplement this machinery in every quote classe.
->What would be the added benefit compare to a more traditionnal =
solution ? (like mine)

I know that you will destroy these arguments in a couple of seconds, but =
it is instructive to understand one's error anyway
