Is this __class__ stuff documented anywhere?
Not yet. Also, we should clarify the proposed private extension section
that only "__some_key" is reserved for downstream, not
'__some_other_key__' (i.e. downstream names must not end with '__').
Why use such weird names at all? What's wrong with 'class'?
That it conflicts with e.g. PCI classes?
Won't the context tell it apart?
Yes, of course, it you need to know the schema. If you don't know the
schema you don't know the context.
This QBuffer thing is something that a client QMP library could create
automatically. Keys in a separate namespace (like '__class__') have the
advantage of being easily picked up automatically by a wrapper of the
JSON parser; if you used simply 'class' such as layer would need to know
a schema, or it wouldn't know that "context".
(BTW I'd prefer something like '__encoding__'; the word "class" suggests
much more than what it is in reality).
