While it's not the best or most efficient way, it is the standard way to extract the unique elements from an array. Do you really want N "uninitialized variable" warnings where N is the number of unique elements in your array?

And, that's just one common usage.

I know you're not answering to me, but to another monk. However that "that's just one common usage" thing seems to me to be a reminiscence of my original post, in which case I'd like to point out that I've noticed it's been misunderstood, well at least about that cmt about a warning, that is. I already posted a reply in which I hopefully explain better what I really meant...
