Thank you Philipp, this is really helpful!
Marshall's guess where *read-eval* from is right. I didn't googled what
does it mean, just left as-is from the Leiningen template.
Talking on replacement to join. For this function I'll link additional
library. My question how this works: in C++ world,
Regarding your question about join: The clojure.string namespace contains
the join function recommended to you. All functions in the clojure.string
namespace, and several other namespaces (see below for a complete list) are
part of the Clojure JAR file, and in that sense come at "no additional

Some versions of the Leiningen `app` template put this in the skeleton
initial source file. I assume that’s where this came from.

Hi Clojure community,

Hi!
If you'd like to use relational structures, take a look at
clojure.set. There's a couple of functions which let you do relational
algebra (project, select, rename, plus some other things like index).
Clojure represents relations as sets of maps:
(def data #{{:id 0 :name "Fred":age 3

Hi all,
I am learning Clojure and would like to see if there is a better/more
concise/faster/more idiomatic/etc. way to create the age-index below. My
version seems awfully roundabout. The basic concept is a toy database table
stored as a hashmap. Each row has a row-id and and a vector of data [n
