grep is a useful unix utility that has a parallel perl operator.
What about uniq?  I'd like to see uniq (or something) that strips
out the duplicates in an array.  It would be cool if it were
built into perl.

Meanwhile, has anyone written an efficient routine to do this?
Linear time would be nice.  I'd like one that doesn't require the
array to be sorted.  I could write one myself, but I thought
I'd avoid duplicating code..
