Review comment:
If we want to assert about R storage type, I'd move the into
`expect_array_roundtrip()` defined at the top of this file, below L30:
```r
expect_identical(typeof(as.vector(a)), typeof(x))
```
so that we can test all types. (I did this locally just now on master, and
only Date fails.)
I also wonder if it would be good to add a test here with `dplyr::if_else`
to reproduce the original issue. IMO the storage mode is only interesting
because of the behavior side effects.
