Fletch and Nevtlathiel have it above. Just in case the code sample is too dense, here's a little "looser" version that does the same thing:

my %seen;
$seen{$_}++ for @content;
my @unique = keys %seen;

[download]
So %seen is the hash that gets a key for each unique value in @content, and @unique is an array containing those (unique) keys.

Do not rebuke them with harsh words ... but rather lead them gently - with URLs - so that they may learn wisdom.
