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

| I want that!  I wanted it years ago.

And it was implemented in Cfront as early as 1983; it was removed, when
some users considered it to be going too far.  Seems like we're back
to the future :-)
