I've fixed this.
The question was originally migrated here from Stack Overflow in November 2011. It was closed today (3 September 2014) by 5 members of the community as being "primarily opinion based", which I agree with. However, when I was cleaning up other rejected migrations that were not adding value, I got over-zealous and accidentally deleted this one too.
I undeleted the post, cleared the migration history (to make it seem like it was always a Programmers question), and reclosed for the reason that the community elected to close it as.
From now, the community can vote to reopen (with 5 votes, as normal) or delete normally. Answers and the question body can be edited and commented on.
