How about this?

class Class
  def class_function(name)
    class_eval { define_method(name, &method(name)) }
  end
end

class Junk
  def Junk.info
    "blah blah blah from #{self}"
  end

  class_function :info
end

puts Junk.info
junk = Junk.new
puts junk.info
__END__
blah blah blah from Junk
blah blah blah from Junk
