My personal unique'ing function is: 
sub unique { my %x; @x{@_} = @_; values %x }

The reason to use values is that I need to get the unique set from an array of objects, not scalars. (This assumes, of course, that every object has a unique stringification. As I don't overload stringification in my objects, this works. If you do overload stringification ... good luck. Seriously.)

And, the reason for not using references is that I use this function as so: 

my @final =
    map {
        # Something
    } unique grep {
        # Something
    } map {
        # Something
    } @start;
