For many R users the magrittr pipe is a popular way to arrange computation and famously part of the tidyverse.

The tidyverse itself is a rapidly evolving centrally controlled package collection. The tidyverse authors publicly appear to be interested in re-basing the tidyverse in terms of their new rlang/tidyeval package. So it is natural to wonder: what is the future of magrittr (a pre-rlang/tidyeval package) in the tidyverse?

For instance: here is a draft of rlang/tidyeval based pipe (from one of the primary rlang/tidyeval authors). This pipe even fixes dplyr issue 2726:

# do NOT perform the source step directly!
# Instead, save and inspect the source code from:
#  https://gist.github.com/lionel-/10cd649b31f11512e4aea3b7a98fe381
# Output printed is the result of an example in the gist.

#> List of 1
#>  $ :List of 1
#>   ..$ :List of 2
#>   .. ..$ : chr "foo"
#>   .. ..$ : chr "foo"

# previously throwing example from dplyr issue 2726
(function(x) mtcars %>% dplyr::select(!!enquo(x)))(disp) %>%
  head()
#>                   disp
#> Mazda RX4          160
#> Mazda RX4 Wag      160
#> Datsun 710         108
#> Hornet 4 Drive     258
#> Hornet Sportabout  360
#> Valiant            225
