select(.data, 0)

[earowang]

It's a corner case. Current select(.data, 0) throws an error. But I would expect select(.data, 0) returns a data frame with 0 columns as .data[, 0].

iris[, 0]
#> data frame with 0 columns and 150 rows
dplyr::select(iris, 0)
#> Error in inds_combine(.vars, ind_list): Each argument must yield either positive or negative integers

Maybe the issue is more related to tidyselect::vars_select().

Thanks. Underlying issue:

tidyselect::vars_select(character(), 0)
#> Error in inds_combine(.vars, ind_list): Each argument must yield either positive or negative integers

When is this corner case important?
