I notice that he mentioned the objection to defining equality and so on for the root object. I have heard this before from Philip Wadler, and the more I think about it, the more it makes sense. This is essentially the idea of removing every method from Object, which we have dicussed before.


I used to discuss against it, but came to realize it does actually make sense.

Java came up with it most likely as it was the way in Smalltalk.

But nowadays we know better, those concepts are better expressed via interfaces/traits/protocols, or whatever they are called in every language.

In languages with generics support and some form of interface definitions, there is no need for root objects.
