I am sorry, but I don't understand still. That's valid D2 code, and I can
understand it. But from its look it seems (beside the not handy syntax, it's
not as adding a "?") the opposite of what I was saying (that by default all D
objects have to be non-nullable). Can you please help me understand? :-)
