Sorry to follow up the same post twice, but..

Thinking again about class definitions returning a value, I wonder how
many people would find the concept of Class and meta-classes more
obvious if the syntax were

  Dave = Class.new {
         }

rather than

  class Dave
  end


That way, the body of the class definition is clearly a set of
executable statements that manufacture a new Class object, rather than
just a passive declaration. It would also help explain why 'attr' is a
method in Module, not part of the syntax.

If a class definition returned a value, not just void, we could teach
it this way.
