# Did this out of interest, only to find out that
# the same functionality already exists in ruby ;-)
# Obviously, I'm redefining extend on Object,
# but it still does the expected thing.

class Object
  def extend(m)
    instance_eval do
      (class << self; self; end).send :include, m
    end
  end
end
