Instead of the clj form to escape back to clojure, why not just use

I assume you mean doing this at the REPL or OS shell. I don't know how
to do it for non-loaded libs, aside from manually walking the classpath,
but (all-ns) might be what you want for loaded namespaces.
Quite right that is an important distinction.

Here is another question on when you would use a multi-method. I want the
mv function to accept a java.io.File or a String for either of the two
parameters and here are the options I came up with:
-(defmulti mv (fn [from to] [(class from) (class to)]))
(defmethod mv [String String] [from to]
Suggestion :
move and generalize the problem by creating an as-file multifn that may take
String, File , and maybe other things later ...
(defmulti as-file type)
(defmethod as-file String [from] (File. from))
(defmethod as-file File [from] from)
(defn mv [from to]
(let [ [from to] (map
Oh, maybe this as-file method already exists in clojure.contrib,
honestly I don't know and don't have the time to search right now,

concurrency feature to manage a multithreaded process elegantly and

I'm not an expert on asynchronicity with clojure, but I'll benefit from the
fact i'll be the first to answer :-)
But please take this with a grain of salt.
As I see agents, in their generality, they are a generic way to handle a
state asynchronously (commands from multiple non organized sources -

The pesky thing about that particular error is that there IS no more
context; it fingers no specific line of code, function definition, or
whatever as culprit.

Hi, I am working on a server project, which requires thousands records

I intend to use datalog to store all my data, sharing the whole

It was a minor thing actually, I didn't like having to quote user
code, and AFAIK, it's not possible to add a quasiquote as part of a

That is a good point. I'm actually not sure why I used type there.
It's probably a bug. Thanks for pointing it out.
