I asked this question yesterday. It has 23 upvotes and 9 stars, which shows the community is enjoying it. It is about programming, about a very real problem (even though it is simplified for the sake of the question), and can be answered objectively (with code). Even more, it's the kind of question I would love being able to Google in one or two years when I will run into the problem again.
Can people please stop trying to close it or migrate it to an obscure Stack Exchange site that has almost no visitors?
