Hmm, doesn’t this approach result in scalability problems? You always have to
analyse the complete input data if a small part of it changes and you always
have to update the complete picture. This is similar to the problems I see
with Yampa-based UI approaches.
However, you might be interested in things like incremental list signals which
I’m (re-)implementing at the moment. To a large degree, the library user sees
a time-varying list but internally the library takes care of not updating the
whole list all the time but only the parts which actually change.

I don’t really understand this. Could you explain this, please?
