too bad one can't define properties in an interface definition,
allowing properties but not allowing interfaces to define properties is 
a bit mmm ... I think it's not complete, I think properties are good, 
but something's amiss here

Properties are methods, not fields. Try this:


interface Foo
{
     int good();
}

class Bar : Foo
{
     int good() { return _good; }

     private int _good;
     this() { _good = 13; }
}

void main()
{
     Bar b = new Bar();

     printf("%d\n",b.good);
}
