I guess I just don't see that as 90% at all. The

Sorry, this is text for second example) I missed this moment. But I think
the idea is clear.
For manual call of __match() type casting can be used:
$orderForCheckout = (OrderForCheckout)$order;
Also this feature can be used for checking e

PHP already has horizontal inheritance. They're called traits.
How is this an improvement in anyway?

I used this example because this is known problem of inheritance. Type
variants solve this problem. Square is a particular case (variant) of
Rectangle.

Yea, but how's that an improvement over using an interface?

How can I check if an order is ready for checkout with interface? The
difference is in property values, not in presence of methods.
You could have an abstract classes implement the interface and extend from

Ok, could you give an example, how to check described requirements with
interface?
Which requirements are those exactly?
