package fails to load on R 4.2.0

parallelly fails to load on the development version of R. This appears to be due to an undefined variable in parallelly_disable_parallel_setup_if_needed() that has the same name as a base R function (rev).

Steps to reproduce:

Install R-devel (4.2.0)
Attempt to install parallelly with install.packages()
See error:

My guess is that the error is here (https://github.com/HenrikBengtsson/parallelly/blob/30c8893ae27158a9f7cf99f56a0dac2fa6d1d012/R/parallelly_disable_parallel_setup_if_needed.R#L32):

} else if (rver == "4.2.0") {
    if (R.version[["status"]] != "Under development (unstable)") return()
    if (length(rev) == 1L && is.finite(rev) && rev >= 80472) {
      return()
    }

In contrast to the if (rver == "4.1.0") { block above it, rev is not defined first, meaning rev is just the base R function. This causes the error "error: default method not implemented for type 'closure'" (At least, that's my bet).
