## digitalmars.D.learn - 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;
```

Yes:

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

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);
