Spécialisations

Il est autorisé à la fois de surcharger et de spécialiser l'algorithme std::swap, mais les surcharges sont généralement préférées car les spécialisations d'un modèle de fonction ne sont pas autorisées pour les classes template. Les fonctions de la bibliothèque standard utilisent toujours les surcharges fournies par l'utilisateur lors du swap, si elles sont reconnues lors de la recherche des argument (d'après le concept Swappable).

Les surcharges suivantes sont déjà fournies par la bibliothèque standard :
