Thanks to all for your helpful replies. Mikel's greet.clj is something

The strings namespace could get rather large then, considering that
strings are how most raw data is represented.

I once wrote a Clojure app that communicates with jackd audio server

calls a couple of native functions, and it works reliably with an audio
buffer of 10ms. I tried it under OpenJDK on Linux.
So the HotSpot VM used in OpenJDK and

I presume that your tests are done in the same namespace as where the
protocol is defined.
For real user code, where the "using" namespace will not be equal to the "+

This is not the whole truth. I think you wrote here (def ark '(test/a-
var test/another-var)). With the above code ark should be nil.
You probably want (def ark (list ...)) or (def ark [...]).

I find this behaviour a little surprising:

Hi,
that's the user's choice. You just provide your + function and the
user has the choice to replace the core + in his namespace with yours.
Or to use some-alias/+ for your +. Or to fully qualify your.library/+.
You can't compromise other peoples namespaces with your own functions.

The point is that I want to be able to use the original one in a

That is if you want to (+ 1 2) still to be 3. Of course you can the

you can always fully qualify the original +: clojure.core/+. Or you

Hi to everyone,
I know that may sound a bit mad, but I need this kind of abstraction
to keep my code as aligned as possibile to a legacy one.
I'm the developer of the clj3D library. I want to overload the "+"
function in order to be able to do this:
(+ "a" "b")
;=> "ab"
or this:
(+ [1 2] [3 4])

I notice that in clojure.core some doc strings contain examples while
others don't. Specifically today I was checking on the arguments for
defmulti and defmethod, and given the doc strings it still isn't
entirely clear how to use them. For example, you have to know how a

There is a real timeable vm from AICAS (http://www.aicas.com/).
If "10s of milliseconds" mean 10 ms - than you will nead a real fast
