I recently came by a question on stackoverflow that mirrored this thread: Merging a list of lists of lists
It's unfortunate that this thread has such a poor title, as I doubt google is going to find it very often. But I definitely remembered your solution and was able to search through all my past posts to find it.
I'm still in awe of your use of uniq on array references, so just wanted you to know that I referenced your code. :)
