(Full disclosure: I have a horse in this race; I think the answer is 'no, but'.)
An answer of mine was closed because a moderator thought it was a clarifying question. However, it was really a leading question, that is, it contained an answer disguised as a question, but the question mark led the moderator to delete, and a potentially useful answer was hidden from view.
What should we do about answers like this? Should we ask posters to repost them more clearly as answers? Edit them to make it clear that they are answers? Delete them and let posters resubmit an answer-looking question?
