Suppport rowwise

[latot]

Hi, I think would be great support rowwise operation from dplyr.

Thx!

Thanks for the suggestion! Will definitely consider it when I'm next working on multidplyr.

A simple workaround for anyone who needs rowwise():

my_multi_df |>
  # instead of rowwise(), make these two calls:
  mutate(row = 1:n()) |>
  group_by(row)
