Ok, the simplest way i see is inserting the elements into a hash as keys,
thus eliminating duplicates, and then do keys on the hash.

Subject: Perl: Finding unique strings in an array
Hi,
Is there some magical way to identify unique strings within an array?
Example:
@array = ( "beer","water","wine","beer","wine");
and I'd like to end up with: beer, water, wine
If there is some kind of function that does this, then I'd be most glad
to hear of it. If not, I'll figure something out with cmp.
Thanks,
Philip
