P.S. This is a question about clarification/advice, not a critique to
Clojure, as it actually works as advertised :)

Well first, there is a conscious split between collection and sequence
functions. Collection functions take a collection and return the same
collection (and take the collection first) - things like conj, assoc,
dissoc, disj, etc. Those functions are all trait-based and "update"
operations are

Hello all
while working on a daily basis where I use Clojure's native vectors/maps I
almost never experience the problem and even if - it is easy fixable with
something like (into [] ...), I have the following problem with custom data
structures and ask here for clarification if my

Hello Mark
the reason was that I want them to act as if they are maps and vectors for
an end user developer and let him work with all the usual Clojure functions
for these data structures, while internally they would have some different
implementation and additional functionality (for
Hi Plamen, I don't have any advice to offer but I'm curious why you want to
bind the table and column type info directly onto the result set. If you
associate them in some other way, then you can just use plain maps and
vectors. Are you trying to have less total objects in your API?

Thanks for explaining Plamen. Yes, it seems very difficult to treat a
database abstraction as a regular Clojure map/vector. FWIW, in writing an
app I think it works well to use SQL queries to return ordinary
maps/vectors which can then be manipulated as usual. But I think you are
doing
P.S. Actually it just a coincidence that in my use case I am not concerned
with let say trees, but with "Records" in a "Table", which in contrast map
somehow nicely to IPersistentMap (where I can put a lot of additional
functionality in a transparent way) and a "Table" (where the sequence
Hi,
I am happy to announce a data-driven application initialisation framework
called Bract.
https://bract.github.io/
Bract provides a first class, declarative way to express application
initialisation config and steps/workflow. Bract has modules for various
purposes, and offers the necessary

This might have nothing to do with it, but, doesn't :import use parens?

Okay, I found my issue, mostly.
It seems that Clojure 1.9 and 1.10 both now have a clojure.core.specs.alpha.clj
file.
This file seems to be the only file that is not AOT compiled by the maven
compile script for Clojure. Thus the Jar for Clojure only has it as source, and
is missing the

Hi all,
I have an inexplicable runtime error with a leiningen-generated AOT uberjar
that happens when using Clojure 1.10 that doesn't happen with 1.9 (I'm on
Java 8 for both compilation and deployment).
The code in question looks like:
(defn make-apns-message [payload]
(let [buffer
Hello James
Yes. The (into (empty table) (comp (filter process?) (map process)) table)
was exactly what I wanted for an end user to avoid to have to write, but
just a (filter ... table), otherwise I could provide a wrapper like (defn
myfilter [pred table] (into (empty table) (comp (filter
