Those look clumsy but you would only use something like that when in fact you define a similar but not the same operation for Strings and Integers. And then the argument-type-suffix would look more natural. For instance:

   saveInt (i)

   saveString(s)

   saveBox(box)

   saveCat (cat)

And then it might make more sense to define classes Box and Cat and say:

   box.save()

   cat.save()
