I know why the implementation lets me ask that question and I know why it's false, but I'd say that there's no reasonable question I'd ever want to ask using that expression.
The point is that the language treats numbers as objects when they aren't.
It's not that reference semantics don't have a place, it's just that the place isn't numbers.
As for your second question, it looks like the type system has two embarrassing questions: what the heck does "new Object()" mean? Nothing worth saying.
I use `new Object()` in my code and I use it exactly for identity equality! If I want a unique ID for something I create a new object and it's guaranteed it will never be reference equality to any other object anyone else could construct.
