Is there an easy way to extend classes with both class and object
methods at the same time?

	module M
	  def self.create
	    # would do something special here
	    new
	  end
	  def objmethod
	  end
	end

	class A
	  extend M
	end

	a.create   # <-- nope, doesn't work

I sometimes have a number of classes that I want to share
implementation, but that don't have an "isa" relationship. Modules are
great for this, but when that implementation includes both object and
class methods, I'm not sure what to do.
