Hello,

decided to contact you directly.
I'm wondering if this can be posted to the group:

Hello,
I'm trying to implement some business model in Clojure. I have several
years of experience developing OO systems in Java. So it's still very hard
to wrap my head to functional thinking. I hope you can help me with
following questions.

I find the modelling Clojure data structures very similar to working out
what your aggregates roots are for domain-driven design or using a document
data store.
I would suggest avoiding using refs in a customer map. In this case, it

But the domain model I'm thinking of has lots of mutable things that
change over time when I execute the business actions.
In your case, you don't need any STM to model any of your domain. I'd go
so far as to say that to use refs for this is almost certainly a mistake.

So far, I really like Garden.
There's one thing though that's making it difficult. It's hard to see that
nested rules are nested.

But i don't find any way to do io blocking operations such as socket.read

Is there a roadmap to make alts! working with java NIO selector that waits

Then we can read/write data with socket/file channel in go without blocking.

Go blocks are GC'd but not until they complete running. The problem is that
you're creating go blocks faster than they can run. Creating go blocks is
very cheap, taking/putting into channels is also cheap but not quite as
cheap. Therefore the outer loop will eventually allocate so many blocks

The obvious approach is to use a future or other thread as an intermediary

I know that readability is a bit of an issue for some people. Unfortunately
there isn't much I can do other than point folks to the defrule macro and some
of the other suggestions I've made. As I work with the Garden I see problem
areas too and am working to find solutions that will
I am not aware of one that does that. I end up using a pom style project. As
a prebuild step I generate the pom using lein. Then my maven step does a lein
validate (basically a dummy step) and then do post build steps that do the lein
commands like lein test. It is not a perfect solution
Right, I understand how defrule works. But I actually do have 27 [i.e.
O(n)] distinct rules, so it's not a feasible solution.
Because when I write CSS, I only style domain-specific class names (.cart,
.license), never mentioning the elements they just so happen to use at the
moment (h1, p, a).
Cool. I'm glad you like the library. Thanks for sharing your kind words and
thoughts. :)
I admit it's weird that it just vector-izes its arguments, and does nothing
else.
In that case I don't think you need a macro, just alias rule to vector and
you'll achieve the same end.
I think it should
