It is unlikely I will find time to read the paper this year, so I could 
be totally wrong. But the original Little Smalltalk used:

  instance ==> class ==> Class

while Squeak has

  instance ==> class ==> metaclass ==> Metaclass ==> Metaclass class +
                                          ^                          +
                                          +==========================+

The three level system was also used in Smalltalk-76. You can't have 
class variables and such with it, which I don't think is such a huge 
loss. Anyway, I think Little Smalltalk has since "evolved" to a more 
complicated system.
