Subject: calling a class method in "class << obj" context


I don't understand this behavior:

  class A
    def A.foo
      p "FOO"
    end
  end

  class B < A
    foo # ==> "FOO"
  end

  a = A.new

  class << a
    foo # ==> undefined local variable or method `foo' for A:Class
  end

Why doesn't the singleton class of a inherit the foo method?

Why does the error message tell me that A doesn't have the foo method?

I've tried:
ruby 1.6.5 (2001-09-19) [i586-linux]
ruby 1.6.7 (2002-03-01) [i586-linux]
