No. I assume you mean seqable.

Hi Andy,
Many collection functions call "seq" on their arguments, therefore
those expect a Seqable (or a String, Iterable, Array, java.util.Map etc.),
not an IPersistentCollection (which coll? tests for).
Working these things out can get subtle.
Thanks,
Ambrose

The first version completes without problems.
Make sure your JVM has plenty of memory available to garbage collect.
Look at the -Xmx setting (for instance with leiningen :jvm-opts ["-
Xmx2g" "-server"])
REPL started; server listening on localhost port 18885
user=> (def atoms '(a b c))
#'user/a
I was wondering cause we can do all awesome stuff like that:
user=> (last "abc")
\c
user=> (first "abc")
\a
user=> (map (fn[z] (str z "-")) "abc")
("a-" "b-" "c-")
but this renders false
user=> (coll? "abc")
false

Because otherwise Clojure wouldn't be compatible with Java APIs. It
would also probably be slower than using the native String class.

How would that affect Java interop? It seems like it would make Clojure
strings incompatible with Java functions that take strings as arguments.

You can use core.logic's unifier:

Maybe I should write a lein plugin that generates a pom for my maven

Hi,
I am experimenting with Clojure since more than a year in my spare
time - e.g., I solved all but one of the katas in the now defunct

Thanks for founding a group.

P.S. Will join the google group right now.

Hi,
I've recently started using the matchure library for pattern matching
(https://github.com/dcolthorp/matchure).
Basically, I'd like match a number of different values and bind the
first match to a symbol. In matchure, binding to a variable can be
done like this:
(if-match [(and ?c "Hi") "Hi"

A quoted symbol is just a literal "symbol" typed object. These symbols
act as functions where they evaluate like this:
('x 1) => (get 1 'x) - look itself up in its argument
('x 1 2) => (get 1 'x 2) - look itself up in its argument with a
not-found value.
So, in your example:
(bar '(foo 1 2)) trie
Oh, I see. This is because of the reader that interprets symbols from the
quoted forms in different way it does for the unquoted ones (and this
feature still strikes me as odd).
To make matters more complicated the quoted symbols seems to have some
meanings as functions for the clojure, since ('
you' are calling (apply 'foo '(1 2)), what you want is (apply foo '(1 2))
just call bar as
(bar (list foo 1 2))

I'm curious why the following form evaluates to 2:
(defn foo [& more]
(println "foo(" more " )"))
(defn bar [v]
(apply (first v) (rest v)))
(bar '(foo 1 2))
If the form (bar '(foo 1 2)) extended to, say, (bar '(foo 1 2 3 4)) the
arity exception will be thrown.
The behavior can be reproduce
Thank you! It seems a good begin.

I just came across this thread (and also [1]) when I was googling for a way
to customize the Clojure agents. Were any of these 'post 1.2' suggestions
reconsidered since then? (I see they haven't been implemented yet).
