How to divide by space keeping words with spaces inside quotes?
Exanple:
string text = "Duck Cat \"Carl Rivers\" Dog";
I want split to:
["Duck", "Cat", "Carl Rivers", "Dog"]
ATENTION: I DON'T WANT:
["Duck", "Cat", "Carl", "Rivers", "Dog"]
How can I get it in Dlang?
regex:
```d
// test with: dmd -unittest -main -run filename.d

return s.matchAll(regex(`"([\w ]+)"|(\w+)`)).map!"a[2] ? a[2]

assert(`"Duck" "Cat Carl`.splitquote == ["Duck", "Cat",

assert(`"Duck Cat" "Carl"`.splitquote == ["Duck Cat",
"Carl"]);

```
