Subject: Class Definition inside a method definition?

I was under the impression that a class definition could not be inside a 
method.
Quote from Programming Ruby

"Method definitions may not contain class, module, or instance method 
definitions."

And yet I've found this source code.

def add_accessor(name)
    methodname = name
    if self.respond_to?(methodname)
      methodname = safe_accessor_name(methodname)
    end
    sclass = class << self; self; end
    sclass.__send__(:define_method, methodname, proc {
      @data[@array.index(name)]
    })
    sclass.__send__(:define_method, methodname + '=', proc { |value|
      @data[@array.index(name)] = value
    })
end

Are singeltons just special?
