My relatively worthless 2c:

union foo {
	int a;
	char *p;
	double foo;
} u[] = {
	{0,,},		/* init the int */
	{,NULL,},	/* init the char *
	{,,0}		/* init the double */
};

Or, similarly:

union foo goo[] = {
	{0,void,void},		/* init the int */
	{void,NULL,void},	/* init the char * */
	{void,void,0}		/* init the double */
};

or very similarly:

union foo goo[] = {
	{0,(void),(void)},	/* init the int */
	{(void),NULL,(void)},	/* init the char * */
	{(void),(void),0}	/* init the double */
};

Seems all that is needed is a way to specify positional parameters,
any of these would do and all have slightly different historical
precedent (the first ",," not C, but macro assemblers.) I like the
first for its brevity (tho it would be error prone) and the last two
for their C-ish style.

Anyhow, that and several hundred million $$ will pay off the nat'l debt.
