Your way works because basically you are building two extra vectors
which are implicitly getting destructured, but that's syntactically noisy
and also a lot of extra computational work that is unneeded.

Thanks!
I cleaned it up a bunch:
))(- (+ (- a b) c) d))]
[z] [(* (/ 1 (Math/sqrt 2))(- (- (+ a b) c) d))]]
(XYZray. x y z)))
After:
(I bet I could use destructuring to shorten the above quite a bit)

Excellent feedback Mark, thank you so much!
This is exactly what I was hoping for. I will be simplifying said code
accordingly and posting it back.
A great way to learn!
I do think I might add
To recap this thread: I started by looking at GitHub's Atom as an IDE for
Asynchronous Learning Engine (ALE), a name I'm using for an
Open Source project. I'm interested in Clojure + Java + Python as
an example flight path through our curriculum space.
Turns out Eclipse is a strong candidate

Gotcha. The answer is
Having done some more research, I see Atom 1.0 is still very new

on the topic (that I could find).
Anyway, it's not a set in stone requirement -- in the virtual school

My day job is teaching Python, but in a school that teaches much else
besides. We're small and I'd say prototypical given how quickly the
technology is evolving.
The description in the blog post below is science fiction from my angle,

I'm new to Clojure (but not to programming) and wanted to document a first
effort.

Excellent feedback so far, I thank experienced Clojure programmers for
giving me tips.
I may post a next version after incorporating some of this advice.
Yes, I have much to learn!

Thanks to excellent feedback, I now realize my code was overly verbose, a
common phenomenon among beginners in many a computer language.
As an example, the newer version replaces this:

Hi,
From a cursory glance, I didn't really understand the domain, so the
function names I used in my rewrite might seem silly. But I wanted to
