Comment (by joaquin):

 Replying to [comment:4 Olaf van der Spek <olafvdspek@…>]:
 > The map variant returns a pointer to second. A variant for containers
 that store pointers performs an additional dereference.

 Why a pointer to second? This is not consistent with the semantics of
 std::map, which returns an iterator to the whole element (the key-value
 pair), not the value alone.

 > IMO the wrapper is useful every time you use a map like container.

 In either case, find_ptr can be provided as an (overloaded) function, no
 need to have as a built-in member function. Thus my reluctance to address
 your request.
