Yes prevention is prob the best way.
But if you must remove dups anyway:
...@array_with_dups in the input array...
my %temp_hash;
$temp_hash{$_} = 1 for (@array_with_dups);
my $array_without_dups = ();
push @array_without_dups, $_ for (keys %temp_hash);
The downside is that thr array order will be messed up...
You can sort it: ... for (sort keys ...
