The motivation for the @dict module is also better understood with a bit of context. Until recently, entries, keys, and values lived in '@iter'. They work on any object, creating an iterator from its properties. Recently the three were moved to '@dict' along with @dict.dict being added. In @iter is now zip and unzip which I haven't seen a description for, but I have a guess at their intended functionality and have roughed it in here https://github.com/Benvie/continuum/blob/gh-pages/engine/builtins/%40iter.js#L18 .
