You never included <algorithm>, and it's std::for_each anyways.

That's a fluke.  One of the headers (perhaps <list>) happens to
include <algorithm>, and using std::list means that std::for_each gets
found by ADL.  Neither are good style, and the first is non-conforming
if <algorithm> came indirectly from a standard header.
