Empty-default operator

[egnha]

Would there be a place for an empty-default operator in rlang?

`%|||%` <- function(x, y) {
  if (is_empty(x)) y else x
}

This is handy in contexts where the notion of "emptiness" you want to check might not be type-consistent (e.g., "empty" names() is NULL, whereas "empty" paste() is character(0)).

We were just talking about it on Slack yesterday :)

[egnha]

Oh, nice! :) (I didn't know there was a Slack channel for rlang ... I presume that's internal?)

[lionel-]

Yes the RStudio channel.

This feels more like a vctrs operator than an rlang one.
