Anyway, one thing I'm running up against is that I am going to need ordered key/value collections, which I believe is something JSON does not support out-of-the-box: "objects" ({"foo":15, "bar":23}) are conceptually unordered key/value collections (and Aeson treats them as such, using hash maps as the intermediate storage format), so I lose ordering;
JSON does not forbid ordering of maps by key, I believe. But you'd need to create an OrderedMap and patch aeson. It would be very useful, the mixing of key order is nuisance for human JSON consumers.
