Way back when I started with Clojure i was doing this:
(let [constant-data (something-expensive)]

But was advised instead to do this:
(def my-fn
(let [constant-data (something-expensive)]
(fn [x]

I found the following work-around since I have access to the java code I am
calling:
I had the package-visible ABC Bytes implement a (public) interface
declaring the toHexString method. This placated the compiler.

Simplified, from a more complex example:
abstract class Bytes {
public toHexString() { return ...; }
Bytes { }
}
public class Hash extends Bytes {
public Hash() { super(); }

This works in Java:
new Hash().toHexString();
This fails in Clojure:
(.toHexString (Hash.))

Edn-java is a Java library for reading and writing edn data.
It has no dependencies other than Java 1.6.x or later.
A more detailed description, including usage examples is available

I find it helpful to view if-let as a minor variation on if, with the only
difference being that you choose to bind the results of the test-expression

I've opened http://dev.clojure.org/jira/browse/CLJ-868
The min and max functions in clojure.core behave unpredictably when
one or more of their arguments is Float/NaN or Double/NaN. This is
because the current implementation assumes that provides a total
ordering, but this is not the case when

dir is a macro. It doesn't evaluate its arguments. So when you say
(dir *ns*), Clojure sees: show me what's in the namespace named
*ns*, and there is no such namespace because *ns* is the name of a
variable which contains the name of the current namespace.
Dir is this way because for interactive

Hi!
Pattern matching is fine for sequence or vector destruction.
Is is possible to destruct map and make pattern machting?
For example I would like to make constraint for to some query service.

You need to tell slurp how the file is encoded.
(slurp path-to-my-file :encoding UTF-8)
That means that you'll need to know what encoding your file is using.
If you've never dealt with encoding before, I recommend reading this:
