John please have a look at Morton's code, he was so kind to explain
what I am worried about much clearer.
That said maybe I can make things clearer myself:
irb(main):001:0> a = class A; ancestors end
=> [A, Object, Kernel]
irb(main):002:0> a.include? A
=> true
irb(main):003:0> B = Class::new
=> B
irb(main):004:0> Bsingle = class << B ; self end
=> #<Class:B>
irb(main):005:0> b = Bsingle.ancestors
=> [#<Class:B>, #<Class:Object>, Class, Module, Object, Kernel]
#Ah too bad my patched Ruby, I gotta recompile, sorry, normally the
singletons are #not in ancestor, please execute the code yourself to
see the difference.
irb(main):006:0> b.include? Bsingle
=> true

Cheers
Robert
