> Before I go implementing changes we need to decide on callback vs list. I
don't see how we can design an interface that supports both (am I wrong there?)
so we need to choose. Seems to be split at the moment. Thoughts?
Agreed. We should not support both. Its one or the other.
IMHO, Callbacks just seems overly complex and less obvious to me. I could
see the value of using callbacks if this was asynchronous, but its not. The
callbacks are made synchronously and so just returning a List seems like the
most obvious approach.
If callbacks more closely aligns with what was there, then just go with
that. Better done sooner than delaying over a small nit like this. I will
assent to either.
