Subject: including singleton methods with a module?

Hi all!

I have a module, which defines several instance methods, and a singleton
(class) method also, which gets use one of the class methods of the
class which includes it.

I.e.:

-------------------------------------------
module Mod
	def self.s1
		do_something_with(helperfn)
	end

	def fn1
		...
	end

	def fn2
		...
	end
end

class C
	include Mod

	def self.helperfn
		...
	end
end
-------------------------------------------

Using like this, I cannot call C.s1(). I suppose I could take out s1
something like this, am I right?

module Mod2
	def s1
		do_something_with(helperfn)
	end
[...]
end

class C
	include Mod
	extend Mod2
end
-------------------------------------------

... Or maybe:

[...]
class C
	include Mod
	def self.s1() Mod.s1() end
end
-------------------------------------------

But, I would like to use my module in my classes as simply is "include
Mod". How can I do this?

Thanks,
Ferenc
