Subject: modules as namespace

i am writing plugins for sketchup and use a module to encapsulate and
protect my variable and methods from name clashes.

Is there any difference between the following?

module A
  def A.say_hi  # or self.say
    puts "hi"
  end
end

module B; end
def B.say_hi
  puts "hi"
end

thanks.
