range-based-for is rather tightly bound with a container. It is not
executed on an arbitrary range. Why not just use a regular for?

    for(auto it  = mymultimap.lower_bound(key); 
             it != mymultimap.upper_bound(key);
 	     ++it)
	     // do what you need

Alternatively, there is a for_each algorithm that we have not yet
studied.
