Ah yes, I see it now. I join the question, a posteriori looks like  
within instance_eval we are in the context of the singleton class of  
D, because D.ii_method works. But puts self does not seem to output  
that one there

   irb(main):010:0> class D; instance_eval do; puts self; end; end
   D
   => nil
   irb(main):011:0> class D; puts (class << self; self; end); end
   #<Class:D>
   => nil

so I don't understand it either.
