Hi,
I see you use the multi-arity form of * - did you know that you can use
that with < and <= too? I think it this improves your function:
(defn params-correct-lucky-numbers
[upto]
(let [max (* 10 1000 1000)]
(if (<= 1 upto max)
true
(do (println "The parameter

I understand that you must use namespaces in idents for logically distinct
types of entities. (Unless you intend them to be lumped together in the
same index.) Thus the

I've just moved to Berwick-upon-Tweed and have a couple months of leisure

be great to meet up with someone with similar interests occasionally. I've

At any rate, I did an attempt at my first macro to create a (def- ...)
form, but it doesn't seem to work. Can you not attach metadata in a macro?

Ah, primes :-)
That was my first foray into Clojure as well. I wrote about it
here: http://www.superloopy.io/articles/2014/learning-clojure.html - you
might find it interesting: my first attempt wasn't so different from yours.

If you don't have time to watch all the talks I wholeheartedly recommend
watching Chris Ford's _Duelling Keyboards_ keynote. Best presented talk
of the conference, IMO. He doesn't go into details about Clojure, but
does go through some live coding and music making. Also, music theory.
