Ok, how to inherit Rectangle, Square, Rhomb, all of which are Parallelogram? In your example Rectangle knows restrictions of Square and any Rectangle is instance of Square. It does not match domain model. 2017-03-13 1:40 GMT+05:00 Yasuo Ohgaki <yohg...@ohgaki.net>: > I pasted wrong URL.

What are these classes? We still cannot use all squares as rectangles and some rectangles as squares without questions. And if we already have one $rectangle with w == h, we cannot just use it as square, we must create new object based on $rectangle data.
