cf. https://style.tidyverse.org/functions.html#anonymous-functions

Currently, we don't lint these:

library(lintr)

lint(
  text = "map(xs, ~ mean((.x + 5L)))",
  linters = all_linters()
)
#> ℹ No lints found.

@hadley is there such a thing as "versioning" on the style guide?

There is a lot of activity on the guide now, I would want to wait for the rules to settle into place for a bit before making the effort to update {lintr} correspondingly. If there is a "version release" that would make this decision making easier.

There should be, but there isn't. I'd say that this tranche of activity has now died down and you can expect it to be ignored again for a while 😄

OK, filed https://github.com/tidyverse/style/issues/233 as an earmark
