If someone would volunteer to fix it, I'd be thrilled. Nobody who is
interested in using CL and Clojure at the same time has stepped

Can you characterize what needs to be fixed?

Hello,
parse-infix, being a macro, works on the code-as-datastructure it has
as arguments.
So (parse-infix x) receives the symbol x , unevaluated, is in charge
of returning a new datastructure (generally involving the symbol x).
Only then, the compiler will evaluate the result of having called

Hello all.
I've started work on a clojure library for interoperating with C. It's
always been a pain to do in Java but recently JNA (java native access)
has taken away most of that pain.
When using clojure however, it's nice to be able to stay in clojure
and not drop to java (or C *shudder*).

Thanks Sean...
Sorry, I should have used a better word than parallel- The second
code example shows what I mean... I'm not referring to multithreaded
parallelism, but simply being able to iterate through two lists in
step, as Chouser describes. (as you can do by passing two different
seqs to map)
At some point, hopefully someone will write an open-source parsing
library with liberal licensing terms for clojure.

The mapping fn itself will be applied to as many arguments as you have
collections. Since + is variadic, it will do the job

There's nothing special about protocols. defprotocol creates a
protocol object
