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

Validators seem like an easy way to do it, I'll try that. Thanks
Chouser!
Afaik Rich only thinks about adding watchers to refs currently, and I
can't find it in the list:

To give some structure to my previous questions - How would I make
refs, that I'm interested in, send an agent on every change, without
having to do that manually?
A: Extend the Ref class (either in Clojure land or in Java land)
B: overload/overwrite (however that would be achieved in Clojure) th

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 obvious

That's great news. Thanks Dave!
Re-reading http://clojure.org/agents I found it mentioned somewhere at
the end, almost like a small, unimportant footnote, easy to
overlook...
Now before I start working on a small and handy framework to handle

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

No, only on commit.

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.

Yeah, it works, but the interface is a little awkward. Rich said he
wants to add watchers for refs and atoms in addition

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

There must be a smarter way to achieve this than polling the
collection for changes, I guess.

Right now, you add listeners to agents, but not refs. IIRC, there
was talk of adding listeners to refs to enable just the sort of
reactive programming you describe, but I don't know the status.

Can I listen on changes done to refs?
Let's say in a scenario like that on
http://en.wikibooks.org/wiki/Clojure_Programming#Mutation_Facilities
could I add a facility that allows the registration of listeners that
get called on certain changes to the refs?
For example I'd like to be notified on
