"yes" voter here... I'm not 100% sure if I understand your concern
perfectly. Evaluating the key as an expression seems to make sense,
specially on examples like:

```
list(
    CURLOPT_GET =3D> $isGet,
    CURLOPT_POST =3D> $isPost,
    CURLOPT_URL =3D> $url
) =3D $curlOptions;
```

Would you mind to elaborate more why do you think this is a problem? :)

Thank you,
