The most straignt forward way is to create a hash slice from the
list by using the list elements as the hash keys and then use
keys %hash (or sort keys %hash) to get a "unique" list.
@hash{@list}=((1) x @list); #create the hash via a hash slice
@list=keys %hash; # get the unique keys in "random" order
OR
@list=sort keys %hash; #if you want the list sorted
If you want or need to, you can create a unique list that
preserves the original order of the list and just eliminates
the duplicates but that is left as an excercise for the reader.
