> Not sure about the API on this because from what I understand from [~bkietz],
> every aggregation function takes a single field ref, but group_by then count
> doesn't require a field because you're counting how many rows are in each
> group. (Perhaps more importantly, dplyr::n() takes no arguments, so we don't
> have a field ref in our expression to start.)
