Why define a clone or equal method in Eiffel gives greater protection with respect to types problems in comparison to something similar in C#?

---

clone and equal don't offer anything great actually. These 2 routines are on their way out, replaced respectively by twin and the operator ~ in the latest estudio versions.

The problem with both of these routines was that don't offer great protection. The both take objects of type ANY (which is a problem). Their new counterparts are much safer and provide better control at compile time.
