That's a great idea. When I get my new phone it will be a great list of
videos to watch/listen to when I commute.
Something that would be really useful would be if there wasd some indication

It is common courtesy on open-source lists such as this one to check if
a question you are about to ask has already been answered. Not only

Hi, I've been using this small project to get some help while working
at the REPL. It's a macro that regroups into one command a set of
useful functions from contrib libraries while auto-quoting it's

Right. I picked a *really terrible* subject line to basically discuss
the question of whether Clojure is the language that answered most of
Yegge's concerns about Lisp adopt
several ideas:
* start the jvm from "emacs" in debug mode
* start the project in debug mode from within eclipse, with an embedded
clojure-swank-server, and connect to it remotely via emacs
the key is "debug mode", where the JVM will be able to reflect *some* clas

Yeah, while doing more testing it seems to depend from where the
ClassNotFoundException is thrown. What I was trying to do at first is
to call extend-type on a Java class only if it exists. Surrounding
extend-type by a try..catch clause doesn't work here. So I tried to

This looks really interesting. Two obligatory questions:

2. Why would I use Midje instead of clojure.test? (Perhaps you can
also blog about it with an example using clojure.test and Midje.)

will do it.
A tidier form would be:
