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);
}
