I can't figure out how to set class variables from class methods
inherited from a module ?

The following doesn't work as I expected (I spare you my others
pathetic attempts):

module MyModule
	def self.extended(base)
		base.setClassVar(base.name.downcase)
	end
	def setClassVar(value)
		puts "self is #{self.name}"
		puts "@@classVar=#{value}"
		@@classVar = value
	end
	def getClassVar
		@@classVar
	end
end

class Class1
	extend MyModule
end
class Class2
	extend MyModule
end

puts "classVar for Class1 is " + Class1.getClassVar
puts "classVar for Class2 is " + Class2.getClassVar

It gives:
self is Class1
@@classVar=class1
self is Class2
@@classVar=class2
classVar for Class1 is class2    # Shouldn't be class1 ?!
classVar for Class2 is class2

Many thanks in advance.
