Recently i created a file object.rb

class Object

I forgot that ruby already reserved this name, so I renamed the class.

But I was still curious. Is there a way to use a “class Object”?

I guess there is no easy way, many things would have to be renamed.

Still, I write this here because perhaps one of you has some idea.

## You could place it inside a module:

module A

class Object

```
def foo
  "foo"
end

```

end

end

## obj = A::Object.new p obj.foo #=\> foo obj = Object.new p obj.foo #=\> NoMethodError

Even if you include it, Object isn’t overwritten:

include A

## obj = Object.new p obj.foo #=\> NoMethodError
