> ARROW-11699 adds support for dplyr::across inside a mutate(). The .fns
> argument does not yet support purrr-style lambda functions (e.g. {{~round(.x,
> digits = -1)}} but should be added.
> As well as this, we should check the new ways in which these functions can be
> specified (n.b. using {{\x}}) as we might want to support both while the
> older way isn't fully deprecated yet.
