C++ Code:
```cpp
std::tuple<bool, int, int, std::string_view> DoIt()

    return {false, 0, 0, "Hello"};

auto [r1, r2, r3, r4] = DoIt();

if (r1 == false)

```


D Code:

```D
Tuple!(bool, int, int, string) DoIt()
{
    return [false, 1, 1, "Hello"];
}

auto result = DoIt();

auto r1= result[0];
auto r2= result[1];
auto r3= result[2];
auto r3= result[3];

if (r1 == false)
```

D requires more lines of code.

I think this is the best thing you can do:

```d
bool r1;
int r2, r3;
string r4;
AliasSeq!(r1, r2, r3, r4) = DoIt();
```

Thanks! It's not concise!
