are you saying that Haskell has amortized, not worst-case performance and so
fast operations need to be paid for ... like when you have to ripple-carry
in binary counting to pay for times when you didn't have to carry the one?

Ilya, where can we find documentation about how to use the new

Good job by the way!

Emacs has this mode with slime and it is very handy in developing web

hi,
Seems like Haskell's laziness has an aura of "it will bite you
performance-wise sooner or later." What is different (I'm asking
didactically, not snarkily) about Clojure's laziness? Does it manage
to avoid some aspects of the "uh ohs" in Haskell?
many thanks.

Thanks a lot for that really detailed analysis Stephen.
I do find "apply" very convenient in a lot of cases, and am using it
to save a line or two of code whenever I can. But after seeing this
benchmark, I think I shall be more disciplined about my use of it.
Especially in the case where the numbe

I'm wondering whether my benchmark is incorrect, or whether there's a

I have a feeling I'm doing something wrong bug I can't figure it out and I

I'm thinking that integer boxing on the argument to your Fn is perhaps
dominating your numbers. I'm not up to date on the compiler, but I'd
think that the argument to the direct Math/ceil call is parsed in
primitive form.

Hi,

telling me that it's a very slow operation. Can someone confirm this?
I'm wondering whether my benchmark is incorrect, or whether there's a
hidden reflection that I'm not seeing.

Hi Kids:
I've been working on integrating Emacs JDB, (command line java debug
interface,) mode with Clojure. It still a work in progress, and has
some funky aspects due to language differences between Clojure and
Java, but you can catch exceptions and bring them up in the source

Thanks, that makes a lot of sense!

Thanks, this is going in the right direction.
The macro expansion looks correct, but the actual execution still
fails:
user=> (macroexpand '(def-fields fs tags))
(def fs (clojure.core/create-struct :name :age))
user=> (def-fields fs tags)
java.lang.Exception: Unable to resolve symbol: :name i
Thanks. On my setup I had to add '(javax.swing JFrame) too.
Pretty neat.

Hi,

true

Hi,
when I evaluate:
(defn digit? [d]
(. Character isDigit d))
(digit? 5)
I get false as a result.
It appears that the 5 does not match the correct type Java expects, or what?
TIA,

If you replace the call to 'symbol' with a call to 'keyword', it works
(I think this is what you intended).

Hello,
Apologies for off topic post.

So far, I found:

I want to write a macro that runs a 'defstruct' using a list of names,
like below:
;; My tag names
(def tags '("name" "age"))
;; The macro
(defmacro def-fields [name tgs]
`(defstruct ~name ~@(map #(symbol (str ":" %)) tgs))
)
;; Using the macro to define a struct based on 'tags'
(def-fields
Well, at least I am not alone.
I think you are right about the emacs/slime thing. Everything just
works if I start a REPL from the commandline and add the classpaths/
librarypaths when I invoke it.
I have tried this on two separate Windows machines with vastly
different configs, so I don't think
