Actually I think python style indention will over-complicate code. When
writing python style clojure you will always need to think in which clojure
with parentheses it will be transformed.
Personally I love parentheses. Imho Lisp is easy and S-expressions are
awesome :)

This should be fine. Both EPL and LGPL are weak copyleft. Clojure code
does not need to be EPL because EPL does not force it. Likewise, Clojure
can call back to this LGPL library because, the LGPL doesn't enforce

Thanks. I did look at the (incomplete) C version, and will take another
closer look before deciding what route to take, but I suspect
an Obj-C/Cocoa version would have different enough requirements to warrant
a new start, or at least a significant re-write.
Cheers,

If you can't run Leiningen on the server you should probably use an

Yes, you're misunderstanding sets which, as implemented in Clojure, are
inherently finite. That 4clojure problem is all about learning how to work
with infinite sequences.

I can see the points being made, and now I'm also thinking that accepting

sequences, like:

Could you try replacing the wrap-resource middleware with the
route/resources function? The latter operates in a slightly different way
to the Ring middleware, and if the Compojure route works without issue, I
might have an idea what the problem is.

- proportional to the size of the smaller set.
Intersecting arbitrary sequences can't be done particularly efficiently.

Good catch with currying non vars; I'll try to work something out. Also,
should come up with a general defcurry macro; I'm not happy with that.
Things like foldM may just not be possible, but I'll keep track of these
issues so maybe I can give you a good answer for the things you've brought
up.
I was just looking for sending data structures. But hey, if RPC existed
