In my thought, Hana is value-first but Fusion (and standard one) is
type-first.
AFAIK, hana always construct via `hana::make` function and deduce it,
like this.

```
auto t = hana::make<hana::tuple_tag>(1, "foo", 3.14f);
```

OTOH, fusion tuple can be typedef-ed, declare value, and construct from
value like hana.

```
using T = fusion::vector<int, char const*, float>;
T t;
t = fusion::make_vector(1, "foo", 3.14f);
```

It's just a style, user can choose what they wanted.
