That page makes no mention of initialization. It merely states that:
"A variable declared with a TypeTuple becomes an ExpressionTuple"

I'm asking about said items initialization scheme:

//----
import std.typetuple;

void main()
{
   alias T = TypeTuple;
   T!(int, int) t1 = T!(1, 2); // OK
   T!(int, int) t2 = 1; // OK?
}
//----

Further, std.typecons.Tuple does not support such an initialization scheme.
