See also JEP-169 "Value Objects". [1]
So presumably terms would be value-ish. Ditto triple and quad.
Graph and dataset collection-ish or even just iterable? I keep an eye
the java lambda discussion, and it would be nice to fit with that. [2]
(although I'm sure I've read an much updated version of this) Stuff like:
graph.filter(...).groupBy(...).into(anotherGraph);
As for equals(), java collections seem to use a form of structural
equivalence and some even work as hash keys (nice, but ewwwww).
