Dylan uses the word `singleton' for little bit different way.  Some
book about CLOS use the term `inidividual method'.

I don't know other languages which have the feature to add method to
individual object, except for prototype-based languages like Self.

Ruby is dynamic one step further so that not only methods, but even
attributes can be added to individual object, using .. uh ..

  class <<obj
    ..
  end

what-you-may-call-it.
