Comment (by Olaf van der Spek <olafvdspek@…>):

 Replying to [comment:3 joaquin]:

 multi_index required a different function, but it can use the same as
 std::set. So it probably shouldn't be a member function.

 should work with any container providing a find member function --I don't
 see the need to have separate functions for map, set, etc.

 The map variant returns a pointer to second. A variant for containers that
 store pointers performs an additional dereference.
 IMO the wrapper is useful every time you use a map like container.
