Thanks for the pointers.

The new feature I most want to use is "auto", which I'm happy to see
has made it into the working paper (I'd heard it had, but thanks for
the confirmation).  See

Right now I notice that some C++ programmers avoid certain standard
interfaces, because of the complicated declarations they would have
to write to use those interfaces. Example:

std::multimap<std::string, std::string> some_map;

instead of

std::pair<std::multimap<std::string, std::string>::iterator,
          std::multimap<std::string, std::string>::iterator>
	     iter_pair = some_map.equal_range(key);

write

auto iter_pair = some_map.equal_range(key);
