I was thinking that Sam wasn't looking for the same interface at both the instance and class levels. I was thinking he wanted the
equivalent of if including Modules also brought in the module levels methods.

module M
  def self.foo
     "foo"
  end

  def bar
    "bar"
  end
end

class A
  include M
end

A.foo # => "foo"
A.new.bar => "bar"

Given the above code is what I think Sam was hoping to achieve, that's why I focused on giving the example of getting that
functionality using include/extend.
