C++ Code:

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:

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:

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

https://forum.dlang.org/thread/kmugmwmduxeoyfffoiif@forum.dlang.org

it's one of those things where D is starting to fall behind competition when it comes to quality of life features

while OP's example is not that bad, the AliasSeq is plain and simple just confusing.. it's a NO

also removing the need of import for tuple is needed!!

it's the same with sumtype/tagged unions and enums literals

we need a workgroup to tackle these issues quick

some new languages are building momentum, it'll be hard to compete when they get released...

we better get ready now and maintain a good balance of new features without forgetting about quality of life

and deprecating/removing old features that holds us back

Thanks! It's not concise!
