Hi,
Is it intended in 1.3-alpha2? I think the error message in 1.2 is way
better (although not as user friendly as I wish to). Shall I report
it? Where? How?

Hello,
I've put some small libraries on github. At the moment they
specifically depend on Clojure 1.2 and contrib (since its the released
version). However, I have had requests to take out the dependencies on
clojure and contrib so that they don't infect projects that use them.

I see your point.
Somehow, it is annoying to have to manipulate a set of protocols that
always go together.
And it would be nice to have a shorthand.
I have a very small prototype here:
git://nicolasoury.repositoryhosting.com/nicolasoury/type-classes.git
of some code to allow "type-classes" like
For complex cases, you may like to fall back on multi-methods and
abstraction types. I blogged about typed abstractions few days ago

I am reading it .. it has nice description of mini-kanren.
I was wondering if there is predicate corresponding to prologs "nonvar" in

Ring has a 1.3 branch to deal with the new version, for example. Maybe
that's one solution.

To me its an implementation wart which is dictated by the use of the
reflection API in the compiler.
There is some work done by Stu to create a clojure reflection API with
several backends (eg ASM or Java Reflection).
However I won't bet on the *current* compiler being fixed.
my 2 cents

Well,
I'm not totally sure about what I'll write below, but I'll still try
to make a decent job of sharing my current thoughts:

"Strong typing" has so many definitions that your statement is nearly
meaningless. See http://www.wordiq.com/definition/Strong_typing for a

I'm not sure what you mean with "strong" type systems. Clojure's
Rich at the Conj explained that he wanted to remove a bunch of
verifications each time a value was referenced to gain some speed.
The basis was of his reasoning was that an unbound
value is an exception more than a common thing and all these verifications at
run time were really slowing things si

I wrote this blog post in the hopes that I can motivate people to
contribute to tryclojure. http://try-clojure.org is a relatively
important website that is unfortunately subpar. I hope that with the
community's help, we can turn it into something spectacular.

Ive recently had troubles using swig in clojure getting a 'unsatisfied

these google groups.

Right. One of the most important aspects of a site like this is it's
tutorial. The tutorial should be interactive, much like tryhaskell's
tutorial. That's one of the biggest things that needs to be done.
Beyond that, tutorial authors would be great as well. If somebody

It seems like the polymorphism of protocols breaks inside the
methods. This is a problem for having a function that's polymorphic
between an object and a container of the same objects.
For instance:

Tune
user=> (deftype Knob [name] Tune (tweek [this] (prin
Last time I introduced someone to Clojure via try-clojure.org, he came
back later and said that the console ignored him after a while, and he
wasn't sure what he did wrong. We tried it together, and after a
couple minutes it stopped evaluating expressions. Does this bug sound
familiar? Unfortunatel
That would be great. Any sort of problems with the console are very
likely to be related to jquery-console, so updating it might fix them.
I actually hadn't heard of that bug. Probably not a good sign, since
it might mean that people spend very little time with tryclojure. ;)

I'd like to remind you guys that if you plan to work on something,
please create an issue for it on Github and let me know, so that I can
assign your name to it with a tag and we can avoid duplicating work.

JRebel is still the best answer. Loading a class at runtime is non- trivial.
I don't know how it deals with handling existing instances of the class,
though; I still think CLOS got that right.
