FWIW, I'd be interested in also:
- Getting rid of WADecoration, it has probably the highest complexity
to utility ratio of anything in the framework
- Simplifying the #registerObjectForBacktracking: mechanism,
especially to avoid using WeakKeyDictionary (I know we all disable
that in production anyway)
- Continuing the work I've started on reducing the number of
Continuation instances created by the standard request/response loop
(ie, only use Continuation for #call:).
