Can I use tidyselect or tidyeval in count()?

[riinu]

I'd like to give dplyr::count() a list of variables to count by. None of these work:

llibrary(tidyverse)
library(palmerpenguins)


varlist = c("species", "island")

penguins %>% 
  count(varlist)

penguins %>% 
  count(all_of(varlist))

penguins %>% 
  count(!!varlist)

penguins %>% 
  count(!!!varlist)

penguins %>% 
  count({{varlist}})
