Yes, the reason I'm delighted with auto is that there are cases where I do not want to know the type (or I want to write generic code that will work with different kinds of containers). For std::multimap<Foo,Bar> amap; when I write auto ipair = amap.equal_range(key); for (auto iter = ipair.first; iter != ipair.second; ++iter) do_something_with(iter->first, iter->second); I explicitly do not want to know the details of the ridiculously hairy type of ipair. If you want to know, it is std::pair<std::multimap<Foo,Bar>::iterator,std::multimap<Foo,Bar>::iterator> and that's with the defaulted template parameters omitted.
