> Do we just want to write bindings for `[[.Dataset` and `$.Dataset` which
map to `select.Dataset()`?
I don't think so: `[[` and `$` extract from an object, and we don't have the
concept of a lazy ChunkedArray. `[.Dataset` would return a Dataset (well,
arrow_dplyr_query)--and in fact it does, it is implemented.
IMO it could either be implemented as `select |> compute` or `stop("[[ is
not implemented for Datasets")`
