placeholder for native pipes

Has it changed? Is there now a placeholder? There is no mention of it
in the help page for "|>" so I guess not, but maybe someone on the
list knows more about future developments?

In an interesting coincidence, support for use of _ as a placeholder
(once per call, in named arguments) in native R pipe has been committed
to R-devel yesterday:
https://github.com/r-devel/r-svn/commit/7cce339c9fc2f61b228d2ea2a022a0cf60d86155

Do you also know for which R release it is planned?

Dear useRs,

When the implementation of the native pipe was announced (e.g. 
https://www.r-bloggers.com/2021/05/the-new-r-pipe/), there was no 
placeholder similar to the dot in magrittr.

Has it changed? Is there now a placeholder? There is no mention of it in 
the help page for "|>" so I guess not, but maybe someone on the list 
knows more about future developments?

Thank you!
Ivan

Not currently, but you can emulate it with the anonymous function shorthand:

(\(.) expression_using_dot ))()

e.g. https://i.reddit.com/r/rstats/comments/nkiavh/is_base_r_pipe_faster_than_dplyr/
