}     #define N (sizeof(void*) * arrlen(vals))
}     vals = getfn()
}     munge_in_place(vals)
}     dummy = zalloc(N)
}     memcpy(dummy, vals, N)
}     setfn(dummy)

Would that memcpy() really work, or would it need to be zarrdup() to copy
each of the elements as well?  Because e.g. arrsetfn() does freearray().
