Can't cast <type> to <type>

[romainfrancois]

library(vctrs)
TestS4 <- suppressWarnings(setClass("TestS4", contains = "integer"))
setMethod('[', 'TestS4', function(x, i, ...){ 
  TestS4(unclass(x)[i, ...])

vec_c(TestS4(3:1))
#> Error: Can't cast <TestS4> to <TestS4>.

May be the same as tidyverse/glue#166

library(glue)
vec_c(glue(""))
#> Error: Can't cast <glue> to <glue>.
vec_c(glue(""))

I'm having serious issues with this lately. I was having issues with glue, but then I updated glue and it went away. I think @romainfrancois used glue_c() to temporarily fix the issues.
Now I'm having issues with {fs}. Using the example on the fs page.

I installed #777 and it works fine now.

library(fs)
library(tidyverse)

iris %>%
  split(.$Species) %>%
  map(select, -Species) %>%
  iwalk(~ write_tsv(.x, paste0(.y, ".tsv")))

iris_files <- dir_ls(glob = "*.tsv")
# I'm reading into a tibble here
tibble(filename = iris_files) %>%
  mutate( info = map(filename, ~file_info(.))) %>%
  # should be one row per file so unnest it so I can manipulate it
  unnest(info)

# nope
Error: Can't cast `info$path` <fs_path> to `info$path` <fs_path>.
