Subject: dynamically read object's attributes

I want to read the values of instance variables in an object, but I
don't know how to reach them.  I think the code should be something
like:

def read_stuff
        s = "Class: #{self.class}:\n"
        s += "Instance variables:\n"
        self.instance_variables.each do
                |var|
                s += "#{var}: #{SOMETHING}\n"
        end
        s += "\n"
end

But I don't know what to replace SOMETHING with.  Anyone know?
