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
