 // This is a simplistic insertion-ordered map.  It behaves similarly to an STL
 // map, but only implements a small subset of the map's methods.  Internally, we
 // just keep a map and a list going in parallel.
 //
 // This class provides no thread safety guarantees, beyond what you would
 // normally see with std::list.
 //
 // Iterators should be stable in the face of mutations, except for an
 // iterator pointing to an element that was just deleted.
