Hi, the library looks very interesting!
I am also working on a rule based translator as part of expresso [1],
my gsoc project Algebraic Expressions, which uses the rule based
translator
to succinctly specify transformations of algebraic expressions.
You can see some examples of this in my recent bl

The most annoying thing to me about forward declaration is that it
prevents what Uncle Bob calls 'Newspaper Style Code' where I can
structure my code in such a way that the high-level functions are
right at the top and the primitives that they might need are found
below so that I or someone else wh

In the past, I've written code like the following
(defn foo [x y]
(let [x-squared (* x x)]
(if (pos? y)
(+ x-squared y)
(- x-squared y
However, the introduction of as-> has led me to write the following, at times
(defn foo [x y]
(as-> (* x x) x-squared
(if (pos? y)
Ah! fnil! That's just what I was wanting, and didn't even know it. Thanks!
I think I like this version best.

I wrote this tutorial up for a friend of mine who is a Ruby programmer
thinking of learning Clojure, as my defense of why Clojure is worth his
time.
I will welcome any advice, code reviews, or suggestions about the post or
code samples.
Thanks!

I have no involvement with this conference but thought some people in the
Clojure world might be interested in submitting talks about big data,
analytics, data science, machine learning, etc.

I think a regular "let" is clearer in this kind of case.
"as->" suggests to me that multiple rebindings will happen to the name: if
that is not happening then it is confusing for readers IMHO.
The only case I can think of where "as->" makes sense and the binding only
happens once is if you are
I personally think the only place as-> should be used is inside other
threading macros. When it's used anywhere else, the name-goes-second
ordering feels wrong and very awkward.

I've found the requirement to define things in order to be a major pain in
the following reasonably common situation:
A) public API in one namespace
B) various functions used to implement public API in another namespace
A clearly depends on B. But B often needs to depend on A also: you

While I don't think I'd use it in your particular example, I like it when
it can eliminate superfluous let bindings.

I agree this is a huge pain, although I don't know if I'd call it a
"forward declaration" issue as much as it is an issue with Clojure not
allowing circular dependencies among modules.
Potemkin seems to be the best way to deal with this particular scenario,
but I personally think that this is an i

Hi Jay
Thanks for the reply. I did not know how as-> works, till I saw your
example. I myself need to many a times chain things where in some cases the
variable will go at the first location and in another cases it will go to
the last location and it was a big pain to do something like what you
