if I have something like

template t(args...)
{
     pragma(msg, args);
}

it prints out args in a tuple... e.g.,

tuple!(...)

I do not want it to print out the tuple!().

I can write my own pragma and pass each arg to it (e.g., 
pragma(msg, arg[0], arg[1], ...)) but this is not very general 
and requires a lot of static if's (one for each possible n).


Is it possible to "untuple"?

template t(args...)
{
	pragma(msg, args);
}

void main()
{
	alias f = t!(int, double, string);
}

Prints `(int, double, string)` for me, with no `tuple!` part. 
However, putting it in a template means you need an alias, so 
it's probably better to make it a function instead.

void t(args...)()
{
         pragma(msg, args);
}

void main()
{
	t!(int, double, string);
}
