I wouldn't be opposed to the addition of this new pipe. The author has a decent argument for it being helpful in some complex special cases. But I don't know if I would want to see this used extensively. IMHO the proliferation of new notation in a quest for ever-more concise code just leads to APL, which most people don't like. Shorter isn't always more readable. The comparison in this example is misleading: # before names(data)[1:2] <- paste0(names(data)[1:2], "_suffix") # after names(data)[1:2] <|> paste0("_suffix") Since we're talking about pipes, the first option should use pipes: # before names(data)[1:2] <- names(data)[1:2] |> paste0("_suffix") # after names(data)[1:2] <|> paste0("_suffix") For pipe enthusiasts this is already pretty clear. The thing on the left and right side of the assignment is the same. Compressing this saves characters and avoiding repetition of the 1:2 part is nice, but I don't know if the cost in familiarity is worth it. In any case involving a data frame, I would prefer using the .cols parameter of the rename family of verbs to either of these base R approaches. Also, a linked post by this author [1] is materially outdated on the use of case_when and across (of course I sympathize - the tidyverse has moved very fast in the past few years). Thanks to the new backslash notation for anonymous functions and various other dplyr upgrades, it is very elegant to do assignment across multiple columns based on conditions evaluated against the entire data frame.

If there is a lack of expressiveness or orthogonality, they will fix it. The R community will take a while to absorb their ideas because there are so many idioms flying around (partly the fault of previous versions of the tidyverse), but the model they've landed on recently is incredible and should be a model for tabular data manipulation in any language.
