digitalmars.D.learn - Simultaneously assigning to all values in a tuple

reply Jamie <notme gmail.com> writes:
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); -- /Jacob Carlborg

Since the question was how to assign to all values in a tuple:" t.expand = Repeat!(2, 1.0); -- Simen
