Why no ICloneable?

by

In addition to Andrey’s reply (which I agree with, +1) – when ICloneable is done, you can also choose explicit implementation to make the public Clone() return a typed object:

public Foo Clone() { /* your code */ }
object ICloneable.Clone() {return Clone();}

Of course there is a second issue with a generic ICloneable<T> – inheritance.

If I have:

public class Foo {}
public class Bar : Foo {}

And I implemented ICloneable<T>, then do I implement ICloneable<Foo>? ICloneable<Bar>? You quickly start implementing a lot of identical interfaces…
Compare to a cast… and is it really so bad?
