Could you explain what you mean by this? I would assume that this would
work:

  class Foo; def bar1; end; end
  f = Foo.new
  def f.bar2; end

  o1 = f.method( :bar1 ).owner
  o2 = f.eigenclass  # class << f; self; end
  o3 = f.method( :bar2 ).owner
  p o1 == Foo
  #=> true
  p o2 == o3
  #=> true

The owner of an instance method should be the class on which it is
defined, right? Thus, the owner of a 'singleton method'
(eigenmethod(?)) would be the (anonymous/singleton/eigen) class. That
would make it easy to get the object_id of that class for the such a
method.
