-----------------------------------------------------------
I noticed another strange NSE behavior inside {{summarise()}}: if you pass
{{na.rm}} as shorthand {{T}} or {{F}} instead of {{TRUE}} or {{FALSE}}, you get
an error like this:
{code:java}
Error: Can't subset columns that don't exist.
x Column `T` doesn't exist.{code}

> 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.
