Fellow Monks:

I've been using the following method to remove duplicates from Array's for quite some time, and it just dawned on me today that I have no why the syntax is the way it is, or even really how it works.

I'm particularly curious why is the unique written as @unique in the first line?

Feel free to shed anymore insight too, as I'm sure others in the forum can benefit too.

my %unique = ();

@unique{@array} = ();
@array = sort keys %unique;

Thanks!
