rather than setting it to `undef`, in which case the hash element still exists, use
`delete`, which also returns the value.
So this could be:
if (my $comments6 = delete $d->{comments6}) {
$d->{comments} = ($d->{comments}) // '') . $comments6;
}
Shorter and also more correct/robust.

shouldn't that include a length check like `scalar($d->{families}->@*) == 0` to be more safe/robust,
as else inet6 could be just be first by chance (did not really checked the context though)

see above regarding use of delete

the length check would not hurt - true. But it does not matter, in which
section (inet/inet6) the comments gets put. The reader method unifies
these comments anyway. So the comment *might* gets put in the inet6
section, event if there is another inet section. Should not matter,
should it?
Will add a "lenght" == 1 to the if.
