Hi, I want to declare a @@class_variable in class A.
Class A includes a Module M and I want some methods in M using the
@@class_variable but I get some problem:

-------------------
module M
	def kk
		#puts (eval %{ #{send('class').class_variables[0]} })
		puts @@class_var
	end
end

class A
	include M
	@@class_var = "kaka1"
end

a = A.new
a.kk
NameError: uninitialized class variable @@class_var in M
        from ./class_attr1.rb:4:in `kk'
-------------------


I understand the problem. Because the nature of class variables when
the Module M uses @@ it looks into a class variable defined in same
class/module.

Is there any way I could use a class A @class_var into a included M
module methods? If not then I'll use a normal attribute but I don't
like it since it's a constant value that could perfectly be a class
variable instead of initialiting it in each A instance creation.

Thanks a  lot.
