--- Comment #3 from Nadav Har'El <nyh at math dot technion.ac.il> ---
Sad, this "fix" removed a useful feature... For example, the OSv project has:


enum class init_prio : int {
    dtb = 101,
    console,
    sort,
    cpus,
    fpranges,
    ...
}

To automatically create numbers for these priorities. This trick no longer
works.
