The below code obviously work the way I wish

module Foo
    def foo
       puts "a"
    end
end

class Bar
    extend Foo
    puts foo
end

however is there any way to get the same effect by using include. I 
would like to mix in class and instance methods in one call. It seems
I can do one or the other but not both at the same time. Is that
correct?
