I have

module A  
module B  
module ClassMethods

def a\_method  
end

# end end end

I would like to be able to

class Klass  
include A::B  
a\_method  
end

==============================================================

the interpreter is complaining that a\_method does not exist for  
Klass:Class

any ideas?

Try this

module A  
module B  
module ClassMethods  
def a\_method  
end  
end  
def self.included(base)  
base.extend(ClassMethods)  
end  
end  
end

class Klass  
include A::B  
a\_method  
end

```
module B

  class_extension do

    def a_method
