I'd put it on Clojars but I can't really figure out how to deal with this
gpg stuff. Seems way more complicated. Wish clojure had something easier,
like homebrew and melpa. But whatever.
GPG signint is currently optional.

There's no syntax for grouping multimethods, but wouldn't it be good enough
to put the defmulti forms near one another?

Thank you very much, I see it now.
1. boxing means from primitive to object; unboxing is from object to

It is not broken. It fulfills the discussed goal of having independent
parallel calls in a let-like macro. Thus the name plet.
Using a previous binding in another binding of plet was no goal. Therefore
you can use the normal let macro.
In a library one should add the intention to use it only

HI,
I come with an update.
Apart from the slow startup time issue, which I can resolve by resuing JVM
or enlarge the splits, there's another factor that influence performance a

which causes frequent young gc, over five

We use clojure on hadoop by using the Cascading framework, it would be hard
to see the influence of clojure on performance because the code is
complicated. But, that means clojure is used mostly to specify the Flow (a
DAG construct) that Cascading provides. That's a way to use clojure that
meant to say, uncontended atom swaps are going to be a bit slower than
setting a java field, but unless you're doing a ton of them you probably
wouldn't notice.

I think it makes sense to consider cache-coherency and message passing to
be on opposite ends of a spectrum, where with message-passing you're
explicitly providing the communication protocol and giving more control,
and in cache-coherent architectures you're relying on the CPU to do it for

Amdahl strikes again! I knew this lunch was too tasty to be free.
I just thought of another analogy. When I think of something highly
concurrent and scalable on the JVM, I think of web request handlers, which
effectively use no memory-sharing for domain-specific work, at all, unless
there is
If the issue is that the GC implementation in Oracle's JVMs typically has a
sequential bottleneck in it with default parameters, then yes, Amdahl's law
is striking *for that GC implementation*.
For problems that are embarassingly parallel (little or no communication or
shared memory between
Ah, yes, I didn't mean to say that things are impossible, a good GC is
already an example of a useful but leaky abstraction with appropriate
knobs. Another example is a database like datomic. I mean that these
tradeoffs and how they change with greater numbers of cores will force our
hands in one
You could do it with `condp`:
(condp #(%1 %2) value
foo-pred? (foo-result)
bar-pred? (bar-result)
