I would like to somehow hide the global hilbert-map into my function,
but I can't see how to do that.
Just put the literal directly into the function.
Is this possible? I know that I can just inert literal into my let,
but that degrades performance, when function is called many times.

Hi André,
I had a similar issue with
Eeeuw.
Was this with a Clojure literal in the let, or with a non-trivial
calculation using constants?
The only difference is literal map of maps in let form.

Hi Stuart,
Can you elaborate on Restlet? After some short investigation I think
it uses annotation but Clojure does not support it, so Clojure is not
Restlet-ready.
