Greetings smalltalkers,
  I'm a newbie trying to get my head around inheritance.  I'm puzzled by the following example.  It seems to do what I mean, but not what I type ;)  This is a good thing, but I'd get further if I understood the semantics a bit better.
  from http://www.cosc.canterbury.ac.nz/wolfgang.kreutzer/cosc205/smalltalk1.html
  Class: Monster
Superclass: Object
Category: Sesame Street
Instance variables: colour tummy
   self colour: #green.
self tummy: Bag new
  "There is only a single class method and no class variables."

   ^ super new initialize
  What I don't understand is this:  Monster new returns an instance of Monster, what you'd want it to. But Monster new executes "^ super new" which to my mind should return an instance of Object, not Monster.  Just to confuse myself further, I typed:
  Monster superclass new 
  and got an Object.  It seems to me that "super new" and "superclass new" should do the same thing.
  Any points to clarify my confusion would be greatly appreciated.
