IMHO, there's no point, just wrap every parameter in a struct. Is 
there really that much of a difference between:

displayCoolName(firstName = "James", lastName = "Bond")

and

displayCoolName(FirstName("James"), LastName("Bond"))

?

It's not even fewer characters! It's not trivial but it's 
possible to make the order not matter by using a templated 
implementation and aliasing it to `displayCoolName`.
