I actually think it would be better to have named parameters. That way:

auto fooval = foo(13, default, default, &foobazval);

is instead:

auto fooval = foo(bar: 13, foobaz: &foobazval);

which I think reads a lot better. I suspect you only want this default
feature so that you can default parameters in the middle of the list
without defaulting those at the end.
