Hands-On Design Patterns with C++

Named arguments in C++

We have seen how collecting logically related values into aggregate objects gives us the side benefit; we can pass these values to functions and access them by name instead of by their order in a long list. The key is logically related, though; aggregating values for no reason other than they happen to be used together in one function call creates unnecessary objects with names we would rather not have to invent. We need a way to create temporary aggregates, preferably without explicit names or declarations. We have a solution to this problem, and had it for a long time in C++; all it needs is a fresh look from a different perspective, which we are about to take now.
