> works, but if you define the expression inline, it doesn't:
> {code}
>   expect_dplyr_equal(
>     input %>%
>       group_by(some_grouping) %>%
>       summarize(has_words = all(nchar(verses) < 0)) %>%
>       arrange(some_grouping) %>%
>       collect(),
>     tbl
>   )
> {code}
> The error you get I think means that {{base::nchar}} is being called. I'm not sure if this is a general issue with our nse_funcs calling other nse_funcs, or if this is about the way the aggregation function environment is constructed separately, but it's not good.
