If you're releasing source, then I think Jozef is correct that you can use

work, then you're essentially releasing something that's impossible for
your users to use according to the terms of the licences. From the EPL FAQ
Hi,
I finally got my robotic vehicle working using raspberry pi. I was hoping

took well over 2 minutes to start. Is that normal or are folks seeing
better performance?

I can give you places to begin at least--recur is a special form and in
Clojure is written in Java,
https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/Compiler.java#L42
whereas in ClojureScript it's written in Clojure:
recur is a special form which is handled by the compiler. The relevant part
of the compiler is at
https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/Compiler.java#L6213
same goes for fn and loop, which are recur targets.

I'm new to Clojure and studying Ring's source to find this would probably
require more time than I have available… this should be documented in the
api shouldn't it?
About providing details, my question was more of the kind what do I have
to do than why isn't it working...
Your description of what is going on with my macro was really helpful. In
my head I was imagining recursive evals running over the code, saying
first, then, etc. I didn't really think about compile time vs. run-time.
I am impressed with James' code as well, but I am having trouble fully

Ok the destructuring is clear to me now. And yes Jay Field article was great :)
So the only thing that remains now is to get the symbol being passed into my

I am trying to use clojure.tools.reader to read from a file and also
process datomic #db/id literals, but I am not sure how to pass in the

clojure.tools.reader.edn allows something like this:

(binding [clojure.tools.reader/*data-readers* *data-readers*]
