Is it possible to have a positional addictional parameter ?

[MicioMax]

Hi,
What I'm trying to achieve is this :

`
const char _1[] PROGMEM = "This is a simple string array";
const char _2[] PROGMEM = "located in flash memory";
const char _3[] PROGMEM = "you can use it almost as a normal C character array";
const char _4[] PROGMEM = "just use 'FSArray(...)' macro to define it";
const char * const _5[] PROGMEM = { _1, _2, _3, _4, NULL };

FlashStringArray flashStringArray(_5);
`

Using something like that :

FlashStringArray flashStringArray = FSArray( "This is a simple string array", "located in flash memory", "you can use it almost as a normal C character array", "just use 'FSArray(...)' macro to define it" );

I guess that I'd need (at least!) the ability to have the MAP applied to a macro with 2 parameters, of which the second parameter is the "position" of argument inside variadic list. It would be possible to have a MAP_POS(F, ...) macro that applies F to all arguments, passing an additional, positional arg to it, i.e.
F(arg, pos), where 'pos' is a number or a _number ?

p.s.: I can't simply use const char * PROGMEM x[] = { "a", "b", .... } because compiler don't apply PROGMEM part to strings but just to pointers of them, so a variadic macro like that is the only solution.
