Hello everybody,
the following code is not producing what was expected of it in clojure 1.2
.. has this been fixed the clojure 1.3?
(let [x (transient {})]
(dotimes [i 10]
(assoc! x i (* i i)))
(persistent! x))

Yea you are right it does not work for anything greater than 8 .. It took me
a while to figure out that the bug was infact the transients.. but did you
try it in clojure 1.3 alpha versions?

Hi Sean,
Yes the two statements are equivalent. ClojureQL compiles everything
to prepared
statements, with every argument automatically paramterized. You
shouldn't have to
call the compiler function directly, ever. For quick inspection,
simply type the statement
in the repl and it will emit the SQ
That is not a bug. You should NEVER use transient and its related
functions to emulate variables - you're supposed to use assoc! and
friends as if they're pure functions. That is, always use the return
value of assoc! and don't rely on its argument being modified.
something like:

Just correcting myself for clarity:

not always in the way you might think. The correct result of these
operations is their return value, bu

Haha! Same here. I have used transients many times too,
I note that the stringtemplate-clj library defaults to using directory
paths only, but StringTemplate itself can pull templates from the
classpath as well. If you placed your templates in
"resources/templates" and used StringTemplate directly, you wouldn't
have to worry about where the template dir

You're not capturing the output of the reduce anywhere; doseq is for
side-effects only.
If you wrapped the doseq in a "(def dictionary ...)" it would work,
but this is not recommended.
Instead, you should either use nested reductions, or produce a simple
list of tokens first (simpler):

No, no new map is created. The :or clause simply creates the local
binding for you if none existed in the map; there's no need for it to
create a second map to do this.
