Struct to hold information about variadic function arguments

Example: Variable Arguments:

public void print_linesv (string fst_str, va_list list) {
print (fst_str);
print ("\n");

for (string? str = list.arg<string?> (); str != null ; str = list.arg<string?> ()) {
print (str);
print ("\n");
}
}

public void print_lines (string fst_str, ...) {
var list = va_list();
print_linesv (fst_str, list);
}

public static int main (string[] args) {
// Output:
// ``first line``
// ``second line``
// ``third line``

print_lines ("first line", "second line", "third line");
return 0;
}
