One option may be Data::Dumper::Perltidy:
$Data::Dumper::Perltidy::ARGV = '-i=4 -boc -nopro';
my $data = [
[[[[["a", "b"], "c"], ["d", "e"]], [[["f", "g"], "h"], [["
["k", ["l", "m"]]]]],
["n", [[["o", "p"], "q"], ["r", "s"]]]], ["t", ["u", "v"]]
[["w", ["x", "y"]], "z"]
print Dumper $data;
Which gives a structure similar to your hand manipulated example:
The perltidy options are explained in the Perltidy manpage.
Update: actually this isn't much of an improvement over the base Data::Dumper formatting due to the -boc option but without it Perl::Tidy compacts the branches too much. So, it probably isn't useful in this case.
