> Didn't we added something_col recently?
I don't think we did. There was `itemsCol` in `fpGrowth`, but it is not
relevant here. ` git grep "_col" | grep "\.R"` shows only a bunch of
<b>_col</b>ors, <b>_col</b>lections and <b>_col</b>lected used for tests and
examples.
`is_grouping` is probably not so fortunate choice, because if column is
used for grouping, it is set to 0.
> Also if `grouping_id(a$col)` ==` grouping(a$col`) maybe we just need one,
`grouping_id` is good enough?
This is certainly a good point, but we won't get away with it. I don't know
if is standard or not but `grouping_id(...)` has to match `groupBy(df, ....)`.
Luckily we don't have to worry about `group_id` :)
