And be careful where you place include Yyy as the placement influences
where the module will be mixed in.

It's different when you do

include Forwardable
class X
...
end

and

class X
  include Forwardable
  ...
end

Sometimes (=rarely), when you want to require later or not at all,
it's useful to put require inside a method.
