extends and implements

[Justin Whear]

You can do this and/or use the convention of extends first, implements 
second:

class Rectangle : Drawable, IShape, IOtherInterface {}

If you're really concerned about clarity, use comments:

class Rectangle : /* extends */ Drawable,
	      /* implements */ IShape
{
}
