Modules in ruby have a lot of similarities to classes (in fact, Class
inherits from Module). Anyway, for this reason, it should make sense that
you want to define "self.yo" instead of just "yo", because it's a
module-level method, not some sort of instance method.

Once you do that, to use the module as a scope, you use two colons. So, the
correct code is:

module Test
  def self.yo
    puts 'yo'
  end
end

Test::yo #=> yo
