There is always something to return from a sub (in some cases, even  undef); if no  return() is explicitly stated, it'll return the value of the last expression evaluated implicitly. It'll do this even if the sub is empty. A return even if you return void (nothing) is one way to show that you specifically mean to exit it, whether due to a condition, or to emphasize where the end of your sub is supposed to be. Sometimes it's handy to say  if ! defined sub();
