You can solve this by casting the dictionary encoded column to string:
`mutate(x = cast(x, string()))` and back to dictionary to get a factor out when
collecting:
```r
d3 <- arrow::open_dataset(temp_file, format = "arrow") |> mutate(x = cast(x,
string())) |>
dplyr::filter(x %in% "a") |> mutate(x = cast(x, dictionary())) |>
collect()`
```
I am of two minds, either we are missing a binding or this is your sign that
`%in%` is not the right tool for the job (at least for single values)
