Can I create Tuple without initialization?

Question

I need to create Tuple. I do:

auto historyTuple = Tuple!(string, "gps", string, "sensor");

I want to initialize with data it's later.

I am getting error:

Error: type Tuple!(string, "gps", string, "sensor") has no value

The value you specified on the right is actually the type of the tuple. You should instead write

Tuple!(string, "gps", string, "sensor") historyTuple;

However, if you intend to use this tuple very often, you may instead wish to create an alias for it:

alias History = Tuple!(string, "gps", string, "sensor");
History historyTuple;
