reframe with across returns an unhelpful error message

[const-ae]

When I call reframe with across and the length of the output is not consistent, the error message is a lot less helpful if the output of across is not named:

library(tidyverse)
tibble(x = 1:3, y = 4:6) |>
  reframe(test = across(everything(), \(x){
    rep(letters[x], each = x)
  }))
#> Error in `reframe()`:
#> ℹ In argument: `test = across(...)`.
#> Caused by error in `across()`:
#> ! Can't recycle `..1` (size 3) to match `..2` (size 12).

tibble(x = 1:3, y = 4:6) |>
  reframe(across(everything(), \(x){
    rep(letters[x], each = x)
  }))
#> Error in names(dots)[[i]]: subscript out of bounds

The situation is slightly better with mutate:

library(tidyverse)
tibble(x = 1:3, y = 4:6) |>
  mutate(test = across(everything(), \(x){
    rep(letters[x], each = x)
  }))
#> Error in `mutate()`:
#> ℹ In argument: `test = across(...)`.
#> Caused by error in `across()`:
#> ! Can't recycle `..1` (size 3) to match `..2` (size 12).

tibble(x = 1:3, y = 4:6) |>
  mutate(across(everything(), \(x){
    rep(letters[x], each = x)
  }))
#> Error in `mutate()`:
#> ℹ In argument: `across(...)`.
#> Caused by error in `across()`:
#> ! Can't compute column `y`.
#> Caused by error in `dplyr_internal_error()`:
