A more recent thread about a Singleton class not being in ancestors
seems to confirm your theory.
Matz explicitly added a check for singleton classes not to be in
ancestor, he was kind of violating smooth flow. I was sure that he had
a hidden agenda in order to do such things, it might be what you said
below.
I nevertheless share the feelings of some others that it is a shame!
Of course if Matz were right I'd love to see the concept and I'd love
to see singleton classes go away, but I feel it is impossible :(.
