How can I detect the last iteration in a loop over std::map?

Question

I\'m trying to figure out the best way to determine whether I\'m in the last iteration of a loop over a map in order to do something like the following:

for

For someone who likes C++11 range-based loop:

    for (const auto& pair : someMap) {
      if (&pair != &*someMap.rbegin()) ...
    }

Notice only reference type works here, not auto pair
