There is a long-standing RfC which basically describes the
same idea on a much wider, conceptual scope. Indeed I consider
this approach used here for solving the problem with GUI uptades
also as a proof of concept, to be expanded to a much wider scope
in case it works out well.
The new insight here is, that, by transferring a diff in pull mode,
we can circumvent the architectural problems with typing, which
showed up quite clearly in earlier design studies towards this
concept. The change from push to pull is by far not so fundamental
as it looks, since the sender still may initiate the exchange
by sending a message offering the diff iterator for the receiver
to pull. This way, we get a handshake and still sustain the
crucial part, which is to decouple the data representation
and give the receiver full control over the interpretation
of the exchanged data.
