Hi, all.
I am reading Clojure in Action.
In the scope section of Chapter3, there are examples like this:
defn twice [x]
(println original function)
(* 2 x))
(defn call-twice [y]
(twice y))
(defn with-log [function-to-call log-statement]
(fn [ args]
Could you please recommend a book that's more up-to-date?

annotate that it is a dynamic var, like so:

With that change, it works in Clojure 1.3 and later.

Hi, all.
I read the following description of `sequence` in the book Clojure
Programming:
* Obtaining the length of a seq carries a cost.
* The contents of sequences may be computed lazily and actually realized
only when the value involved are accessed.
So a sequence is something lazy,
the worst case which is a traversal of the whole
sequences -- plus if the sequence is lazy (and not yet realized) the
traversal will cause its realization.

Hi, all.
I am following an example demonstrating that `transient` can help optimize
mass updates to data structures:
First, a function is defined, which doesn't use transient collection:

This is supposed to run slower than the

Hi, all.
I notice that in every directory that I have runed `lein repl`, a file
named `repl-port`is generated.
I wonder if it's possible to set things up so that this file is not
generated, or maybe I can set up some directory for these files.

Hi, all.
I am playing with the `ring` library in `repl`.
After using `run-jetty` to start a server,
I typed `ctrl+c` to send the SIGINT signal,
this ended the `run-jetty` function, but it didn't kill the server:

-server command in terminal, be it `python
manage.py runserver` or `lein run`, I would use ctrl-C to stop the process.
`run-jetty` is just like other functions, it returns the server object.
