The difference is: foo(10, default, default, default, 12, default) vs foo(.x = 10, .z = 12) Some people might find the second easier to read and understand. (And some might prefer the first because it doesn't "hide" as much.) Tony -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.

The IDE showing names doesn't help much.=A0 The differenc= e is:

foo(10, default, default, default, 12, default)
vs
foo(.x =3D 10, .z =3D 12)
