Support default values for named arguments #54

Open davidbrochart opened 3 years ago

Is it possible to write something like this?

void displayName(FirstName const& theFirstName = "James", LastName const& theLastName = "Bond");

Oh, I guess simply:

void displayName(FirstName const& theFirstName = "James", LastName const& theLastName = LastName("Bond"));

Actually default values would be interesting when combined with out of order arguments (at the end of this blog post), so that we could write:

displayName(firstName = "John");
displayName(lastName = "Doe");

But I guess this would be very hard to do?
