I posted this last time aroundposted this last time around, and I think it still has value:
A user flags (as low quality or NAA) an answer that consists of only code -- no explanation, no references, just code. On the one hand, the answer is (1) correct and (2) self-explanatory to an experienced user of the language/tool in question. On the other hand, it's possibly meaningless to the OP. Do you delete the answer?
