Hi,

I can't explain the semantics for normal case, for example, in

  class Foo<Bar
  end

Foo is undefined at the point.  Thus I don't think I will accept
this.

|An alternative might be to have Struct.new do a class_eval:
|
|     Struct.new(:name, :ago) do
|        def to_s
|          ...
|        end
|     end

This is much better.  Will be available in 1.9.
