> 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.
