Building on Michal's example, here is a "more minimal example" --
which also "fails" in Clojure:
(ns test

(defmacro silly [obj pat1 body1 other]
`(case ~obj
~pat1 ~body1
~other))
(let []
(def out (java.io.StringWriter.))
(defn log
Hmmm, looks like I can replace
#(not (nil? %))
by
(complement nil?)
which seems more elegant.
Also, it looks like I don't need that (into [] ), which will keep the code
cleaner.
I think I could also get rid of the (or) by always adding "(last params)"
at the end of the sequence from which I

Hi, Joerg.
When I have a sequence I want to split into sub-sequences, I use the
partition.* functions:
(->> your-seq (partition-by string?) (partition 2))
will get you very close to your solution.
A slightly lower-level technique if you need more control is to construct a
lazy sequence yourself
All good points Andy. Thanks. I'll continue working on it until I'm happy.
I am almost never happy with anonymous functions either. In this particular
case, though, the function is so simple that I felt it would be overkill to
externalize it into another function (unless I'm really going to use
Hi Michal,
Does this mean:
(a) the reported behavior is normal (and my bug report is invalid) or
(b) this error happens in both cljs + clojure ?

All the good feedback here had me thinking a lot... Especially Andy who
pushed me towards more abstraction.
I loved the idea of functions that return functions and researching all
this led me to embrace "partials".
Here is my current implementation of "quantize". It came out of a lot of
trial a
so, each string(type) is used as a grouping-key, which prefixes every each
following string-in-a-vector as an argument to myfunc in the result list.

Glen,
I did start the implementation in Clojure, but had to move it under the
skin of PersistentHashMap to achieve what I needed, so it is now written in
Java and is part of PersistentHashMap... I don't think it would be
practical to make it an add-on - but it would be nice :-). I'll keep it in
Alex,
thanks for the suggestion - I'll look at collection-check and raise the
appropriate JIRA when I am happier with the code / idea.

I've started doing some more serious testing and have not encountered any
problems so far. I was a bit worried about the interaction of splice and
transient/persistent!, but have not encountered any problems yet. I am
going to read through the code again to satisfy myself that there is no
issue
Can anyone verify whether this bug is reproducible?

Hi,
I'm fairly new to clojure as well, but I like this way, and I *think* it's
idiomatic:
Data structure:
[{:zone-max 100 :zone-key :hr-zone-1}
{:zone-max 120 :zone-key :hr-zone-2}
{:zone-max 140 :zone-key :hr-zone-3}
{:zone-max 160 :zone-key :hr-zone-4}
{:zone-max 333 :zone-key :hr-zone-5}
:eval-in can be overridden in your project.clj, just add:
:speclj-eval-in :subprocess
I agree that the default is rather odd - especially when the only reason
I'm aware of is "it's a bit faster"
Cheers

Is there a specific part of this implementation which means it needs to
live in core?
It would be cool to have this as a library that could be used with existing
versions of clojure (I have no idea if enough of the internals are exposed
to make this viable)

CLJ-700 is a bug, regardless of whether it is marked as alpha or not.
This ticket has a strange history of approval statuses (pre-dating my
involvement with jira) that caused it not to be included in 1.6 earlier.
Unfortunately, I think it is too big a change to consider at this point in
1.6 (d
Since transients are no longer marked as alpha, I want to take this (last?)
chance to raise an interface question concerning them:
Right now, we cannot distinguish whether a transient contains a key with a
nik value or if it doesn't contain the key, because contains? doesn't work
on transients.

Wow, thanks Gianluco, Andy and Bruno. Lots of good feedback I am trying to
process. It's amazing how coming up with a satisfying "functional
programing" style function is a complex process when you've been doing
imperative programing all your life. It's really a whole different way of
thinking.
It is too late, but an enhancement jira would be appropriate. I would
highly encourage some generative tests in such a patch and perhaps looking
at https://github.com/ztellman/collection-check. With simple.check moving
into contrib as test.check, we expect to be able to use test.check within

Hi Jan,
Thanks for your explanations.
I have no idea how I managed to completely misunderstand

me.
I've decided to switch to agents.
