I see why I'm confused now. Take this example:

  --------------------------------------------------------- Marshal#dump

  <snip>

         o = Klass.new("hello\n")
         data = Marshal.dump(o)
         obj = Marshal.load(data)
         obj.sayHello   #=> "hello\n"


Dump is being used as module/class method so shouldn't it be 'Marshal::dump' ? 
The documentation says they are instance methods, but you can't initialize a 
Marshal. What gives? 

(Is Marshal singleton, BTW?)

Thanks,
