Nice variation of the problem.

```@arr = (
[ qw{ ein zwei drei } ],
[ qw{ one two three four five } ],
[ qw{ un deux trois quatre } ],
[ qw{ uno due tre quattro cinque sei} ],
);;

push @xformed, [ map{ shift @\$_  } @arr ] while @{ \$arr[-1 ] };;

print pp @xformed;;
(
["ein", "one", "un", "uno"],
["zwei", "two", "deux", "due"],
["drei", "three", "trois", "tre"],
[undef, "four", "quatre", "quattro"],
[undef, "five", undef, "cinque"],
[undef, undef, undef, "sei"],
)

Now that's very neat! BrowserUk++

Not so neat after all. It relies on the fact that your data had the biggest sub-array last. Move it to any other position and it fails. You still need max() for a proper solution.
