Well, there is also a third way, half-way between the
"Boilerplate hell" and that DIP, that avoids `res` variable:
```d
import std.meta;
import std.typecons;
Tuple!(int, string) getResult() {
return tuple(404, "Not Found");
}
void main() {
int code;
string msg;
AliasSeq!(code, msg) = getResult();
}
```
Having a way to both declare and assign in one statement looks
great. Hopefully this DIP would be also implemented and merged
quick enough to not get lost for years.
