Review Comment:
It is possible to avoid clone
```suggestion
let (keys, values): (Vec<_>, Vec<_>) =
args.into_iter().enumerate().partition(|(i, _)| i % 2 == 0);
let keys = make_array(keys.into_iter().map(|(_, expr)|
expr).collect());
let values = make_array(values.into_iter().map(|(_, expr)|
expr).collect());
```
