Especializaciones

Ambas especializaciones personalizados y sobrecargas del algoritmo std::swap están permitidos, pero las sobrecargas son generalmente preferidos desde especializaciones de una plantilla de función no están permitidos para las clases de plantilla. Funciones de biblioteca siempre utilice las sobrecargas previstas por el usuario cuando se cambia, si se encuentran con argumentos que dependen de búsqueda (como por concepto Swappable) .

Original:

Both custom specializations and overloads of the std::swap algorithm are allowed, but the overloads are generally preferred since specializations of a function template aren't allowed for template classes. Library functions always use the user-provided overloads when swapping, if they are found by argument-dependent lookup (as per Swappable concept).
