Thanks everyone for their answers and extra efforts. They are really
helpful.

Hi there,
I've written a new test runner for clojure.test. It does 2 main new things:
parallelization, and *much* better output, error reporting, and some
surrounding formatting/running features.
All the features were extracted from stuff I've accumulated in my app's
user namespace over the la
It does seem as though there is no way to meet all the criteria, unless the
support for it comes from Java/Oracle. That said, I feel like having a
complex type with reasonable performance is better than having nothing at
all.
What I would like is a complex type that plays well with Clojure's g
Your messages are a bit confusing. Playing nice with collection functions
would depend on the collection, not on its contents.
Maybe you could elaborate a bit more on what you're trying to accomplish?
If you do not care about performance, you need to decide whether you want
your type to work with
My two cents:
I started to develop some support to complex numbers in Clojure, but I
don't know if the Core Team/Rich Hickey has any intererest in this subject.
Even it's an unfinished work, I didn't notice any lost of performance so
far.

This library is pretty interesting, but you might want to change the
single-segment namespace you have. A single-part namespace is compiled as a
bare class without an associated package, and this can result in issues
around Java interop and AOT compilation. While a single-segment namespace
is likel
To put is simply, it would be nice to have a complex type in Clojure, not
as a separate namespace, but something that is part of the language. It
should interoperate with other Clojure types (like adding a double to a
complex), as well as clojure.core.arithmetic. That's what I meant about
playi
Most of Clojure's collections already can hold arbitrary type values inside
of them, with no additional work required, whether those types are built
into Clojure or not. That is because most collections treat all contained
items as Java Object references.
The only exceptions I can think of are th
Not that tricky, really. But there's a lot of repetitive work.
I changed the Clojure readers to understand the a+bi format, created a
ComplexNumber class and changed the class on charge of arithmetic to work
with complex numbers.
So it's possible to make any operation mixing Numbers, Ratios and
C
What would you say is the most complex, hard-to-grok code in Clojure
codebase?

Hello, all,
I've brought up the idea of some sort of Clojure community organisation
a few times on this mailing list. The ideas is to help grow the Clojure
community by doing things like supporting GSoC students, run
infrastructure like Clojars, help run conferences, etc. I have decided
to start
I'm running into a strange exception trying to handle exceptions within a
go block. So far this is the simplest test case I've gotten to fail:
(ns test-async
(require [clojure.core.async :refer [go >!]
:as async]))
(defn test-chan
[chan]
(go
(try
(>! chan)

Many choices….
We can start from BitmapIndexedNode assoc:

although you might argue that if you read

Persistent collections, STM, and the compiler are all deep veins. One may
also muse on how these were also some of the earliest things in Clojure.

I think this is a bug in the fairly old tools.analyzer version used in the
latest released version. That's actually been updated for the next release
and does not seem reproducible to me there.

You can do virtually all of that already with the Apache commons Complex
class. Any Java object can be just fine used with map / reduce / filter /
seqs etc.
If you want to avoid Java interop and make things more "Clojure-like" then
a lightweight wrapper library is all that is needed (my suggest

How do we use a container class with a proxy?
Given the following class signature, how would we write the proxy?
```java
public abstract class FooInitializer
```
```clojure
(proxy [FooInitializer ???] []
```
