yes, it works; just i dunno yet how to make it work with Data::dumper, but without it no problem. just use foreach to print: foreach (@list){ print "@$_\n"}

Thanks mikevh for your response. I've never used sort inside of a map, and it took some time to figure out, so the solution should be like this: map { @$_ = sort { $a <=> $b } @$_, $_ } @list;
