Should we provide a linter to statically detect unsupported currying of base functions?

[IndrajeetPatil]

Although R CMD check can detect such usages, it might be a nice feature to detect this statically.

dir <- withr::local_tempdir()
withr::local_options(list(usethis.quiet = TRUE))
library(usethis)
pkg_dir <- create_package(dir, open = FALSE, rstudio = FALSE)

withr::with_dir(pkg_dir, {
  usethis::use_mit_license()
  fs::dir_create("R")
  writeLines(
    c('f <- purrr::partial(gsub, pattern = "/$", replacement = "")', "NULL"), 
    "R/script.R"
  )
  
  rcmdcheck::rcmdcheck(error_on = "warning", quiet = TRUE)
})

That said, I am not sure how to get a list of {base} functions that call .Internal().
