JSON in OTP

[Max Lapshin]

First simple question:  how to decode json objects into maps if json
declares order and erlang maps are unordered?

If you decode json object not into maps, then nobody will use this
module, because it is very inconvenient.

Second question: atoms vs binaries as key values. You have different
decoding for different sources (trusted/not trusted).
Very inconvenient situation =(

And so on with other questions.
