Ruby - can you create a standalone object like in javascript?

Question

In javascript, you can create blank objects that are not an instance of anything. Like so:

foo = {
    bar: 12,
    fooFunc: function() {
        return this.bar;
    }
}

Is this(or something similar) possible in ruby?

You can singleton an instance from Object and that would be the same. — Benoît

also take a look at OpenStruct which allow you to add attributes at later points — timpone

Ruby has an Object class from which all other objects inherit. From the Ruby docs:

Object is the parent class of all classes in Ruby. Its methods are therefore available to all objects unless explicitly overridden.

Object mixes in the Kernel module, making the built-in kernel functions globally accessible.

In Ruby 1.9:

Object.new.class #=> Object

Object.class #=> Class
Object.superclass #=> BasicObject

BasicObject.class #=> Class
BasicObject.superclass #=> nil

I will indeed, but I am required to wait another two minutes before it lets me.
