I read this question when only this answer was present. I knew of other answers, but since there are so many possible answers I chose to give several of them giving use cases for each (e.g. the first solves OPs question, but isn't very flexible). I then got a nasty comment saying "So after everyone has answered, you make a summary of it and then write a new answer? How convenient." after which 3 downvotes followed.
So I ask, is what I did reasonable? I honestly only "copied" (even though I knew it already) the first answer. The others appeared while I was typing up my answer. But my answer was quickly accepted so I'm hesitant to delete it or remove anything from it. Should I go back and reference the other answers (which were posted while I wrote my answer), even though I came up with them myself?
Putting the fact that the other answers appeared while I was putting together my answer, does a grouped answer not have more long-lasting value than 15 scattered answers?
