I'm not exactly an STL hacker, so I wouldn't know if there's a more elegant
solution, but here's my idea:

You can maintain a namespace with pointers to arguments for
write_to_player() and empty-out the arg-list of write_to_player() (and
probably write an inline wrapper to map from arg-list to this namespace for
normal calls). Then intially set up to_send and add_eoln in that namespace
and call for_each() with begin and end. This will work here because the
arguments are common.
