wrong, wrong, wrong. 

Your examples only show that the restriction to named classes doesn't formally restrict the expressiveness of the language (since you can always introduce "gensym'd" class names in a place where you would use a class expression). 

The point of the "divisive issue" was not that the restriction to named classes only makes the language formally less expressive, but that 
- nested expressions it make the life of tool implementors harder
  (simple example: the clunkiest part of OILed is editing these nested 
   unnamed expressions), and also it makes the
- they are one of the hard parts for people to learn/read in the language
- many appliers report that they only use named classes anyway

So, the issue is not a formal simplification, but a pragmatic/conceptual simplification. 
I though we went through all this in A'dam?
