Just a caution. Validators can run even if the ref does not change.
For instance when a transaction is aborted by another validator.

Apart from being blasphemous - would it be a good idea to override
clojure.lang.Ref in Java land?
I want to create (children of?) refs in clojure that send an agent
when they change, so that I can create facilities to observe changes
to them. Creating a 'MyRef extends Ref' seems to be the

Afaik Rich only thinks about adding watchers to refs currently, and I
can't find it in the list:

If Rich adds watchers for refs, would watchers be notified inside the
transaction?
I'm actually trying to get a notification after a transaction
successfully finished. Although there might be use cases for firing
events inside the transaction.

No, only on commit.

Well that's easy. Agent sends are buffered in a transaction, and only
sent upon successful commit. The coolness of this is hard to

If you search the group for cells you'll find quite a bit of

There must be a smarter way to achieve this than polling the
