-0 for the addition to the collections module, -1 on the specific
name.

Java made a *big* mistake by putting "Hash" into the names of these
things. From the outside, it is primarily a Dictionary; only when
you look closer you see that this specific dictionary requires
hashable keys (as opposed to, say, the C++ std::map, which requires
sortable keys).

So consequently, the data type should be called OrderedDictionary,
and its cookbook recipe is
