FYI that package is here: https://code.dlang.org/packages/jsoniopipe
I really want to start using it, but priorities.
It should be pretty functional, but it's a bit hard to use at the moment
(unless you just want serialization). I need to work on the parsing API.
The benefit is it allows parsing the JSON without constructing some
tree-like representation of the data. The serializer uses this directly,
which makes it fast. Probably not as fast as asdf, but I could maybe get
it there with some tricks.
