Simultaneously assigning to all values in a tuple

Is it possible to assign to all values in a tuple at once if they are the same type?
I.e.

Tuple!(double, "x", double, "y") t;
t[] = 1.0;

foreach (ref member; t.expand) {
    member = 1.0;

Yes:

Tuple!(double, "x", double, "y") t;
t.expand = AliasSeq!(3.1, 4.2);

Since the question was how to assign to all values in a tuple:"

t.expand = Repeat!(2, 1.0);

t.expand = Repeat!(t.length, 1.0);
