Hi,
Is there an easy way to get all the unique elements of an array? i.e. is there some module or function that does that sort of thing?
Hmm, none of the solutions so far have been stable. In other words all the solutions so far modify the order of elements from the source array. How would you implement a version of the function that produced an array where the elements are in the same order and only the first of any duplicates are kept?
( a b c d e f g h ) == stable_uniq( a b c d a b e f c g h )
