Take a look at the  uniq() function ...

I second that.

Your code seems to be too "tricky" ...

Too tricky by half. But if you are going to recommend 'simple' code, at least recommend the idiomatic version: 

>perl -wMstrict -le
"my @ra = (1, 3, 2, 3, 2, 3, qw{X b X c X});
 my %seen;
 @ra = grep !$seen{$_}++, @ra;
 print qq{@ra};
"
1 3 2 X b c
