in reply to sorting an array of hashes and removing duplicates

Another way to do it might be to just run the output of the sort through another filter like so:

my %seen; my @sortthetutors = grep { !$seen{$_->{tutorsID}}++ } sort { $a->{tmiles} <=> $b->{tmiles} } @tutorsdata;
-enlil

    This one worked beautifully, I tested it on 80,000 records, it took just a couple seconds...

    Thanks!!!
