What is meta? ×  Question: How to generate permutations where
a[i] != i?  This was just closed as "not a real question", but I
have no idea why:  It's easy to tell what is being asked here.
This question is not ambiguous, nor vague, nor incomplete, nor
overly broad, nor rhetorical and can be reasonably answered in
its current form. So it fails every test for "not a real
question".  And yet a moderator came by and closed it up. Can
someone please enlighten me as to why?  share|improve this
question It's reopened now. My two cents: the way the question
was asked (Now I need to generate all permutations...) might
have resulted in some users flagging it, and the mod acting on
these flags. –  Frédéric Hamidi Dec 5 '11 at 7:20 It did in fact
get a VLQ flag, and a moderator did act on it. –  Robert Harvey

The original edit was more or less a statement... Not a
question.  After someone came along and edited it, it became a
gimme da codez question.  Person
