This does actually look like a pretty straightforward typo in `forward_list`; the other containers all seem to get it right.
It's too bad that none of our tests notice the change; but, the POCCA/POCMA/POCS traits are obscure, and this affects literally nothing but `-std=c++11` mode. I don't think it makes sense to hold up this patch for lack of tests.
(@airglow923 please wait for an approval from "libc++" before landing. @ldionne ping! am I missing anything subtle here?)
