can you reference elements of an array/hash from within that array/

See Data::Alias and Array::RefElem.
perl -Mstrict -MData::Dumper -MData::Alias -wle '
my @data = qw(A B C D A E F A B B A);
for my $i ( 0 .. $#data ) {
Better: for my $i ( 0 .. $#data - 1 ) {
for my $j ( $i + 1 .. $#data ) {
next if $data[$j] ne $data[$i];
alias $data[$j] = $data[$i];
}
}
$data[0] = "X";
print "@data";
print Dumper( \@data );
