BTW long ago I wrote some patches to cross check all the values in the
table (since there is redundancy in what we store there), but I was
too annoyed at having to do that cross check at runtime that I didn't
send the patches out. I was slightly hopeful that C23 constexpr could
save us, but apparently constexpr for functions didn't end up in in
the spec, so likely not really useful :(
