This isn’t necessarily so, though. I don’t see why unchecking the checkbox can’t create an Option<T> that is passed (int value, bool false). It just means that you accept this as a valid construction state, and that it must therefore be handled.

I admit that I might be missing something fundamental to this discussion.

I meant to say "saving application configuration as Option<int> (either int value or None) is easier for the application to read correctly then a tuple (int value, bool present)."
