Override member variables

[Gheorghe Gabriel via Digitalmars-d]

I've worked with a lot of programming languages and I've found 
something interesting in Kotlin. You can override member 
variables. Would you like to have this feature in D?

class Rectangle {
    int width = 0;
    int height = 0;
}
class Table : Rectangle {
    override int width = 10;
    override int height = 14;
}

In my opinion it's a more cleaner sintax and you don't need to 
put them in constructors. When you look at the Table class 
definition/documentation you see that it changes width and height 
and their new default values. I am curious about your opinions. :)
And of course, you cannot override private members.
