I would like to ask why How to force evaluation in Haskell? was down-voted and closed. This came completely unexpected since it is a very specific and precise question regarding Haskell and how to force evaluation of an expression. There are tons of similar questions on programmers.
As far as I understand, a few question have been cleaned up (and possibly moved to stack overflow) in the last few days and this question was too old to be moved. I admit I was a bit confused about which questions belong on stack overflow and which belong on programmers because I have seen quite a number of more technical questions on programmers (e.g., if I am not mistaken, this, and this) that IMO are a bit on the borderline.
However, I have seen that some of these questions have been moved to stack overflow so it is a bit clearer now. Still, I would find it better if it was possible to move also old questions: the question had already an accepted answer.
I have posted a copy of the question and answer on stack overflow, as discussed with the moderators.
I would now like to delete this question because (1) it is off-topic and (2) for some reason it got a downvote and I would not like it to get more. But it is not possible to delete the question because it has already an answer. What can I do? Thank you in advance.
