I see, I am reading that "Extending Java Classes using proxy" article.

gettingclojure.com currently redirects to www.wikidot.com.
www.gettingclojure.com is fine, though.

Great working, thanks! I will participate actively.

Excellent. Seems to work quite well.

One example is a contract programming job I did recently, writing
software for identifying radioactive isotopes based on measurements of
their emission spectra. In the end I had 7 Clojure source files (not
including tests). I will show them in such an order that each file
depends only on previous f

how doesn't it work? the approach of writing your library using
regular functions while protocols provide a simple pluggable lower
bound that users can implement. and when users do implement the simple
protocols they suddenly get all the advanced features of the library
functions, like if you imple

No, you have this backwards. The protocol is not on Object, Object is on the
protocol. Protocols live in namespaces. You can have 10,000 different protocols

1. The "declare" macro may be handy for declaring multiple names at
once.
2. Maybe one could use the functions in clojure.repl or clojure-
contrib.ns-utils to write something that automatically forward
declares everything needed?

Hi all,
A while ago I hooked Slime's completion and documentation features into the
popular Emacs auto-completion framework "auto-complete"
(http://www.emacswiki.org/emacs/AutoComplete).
Since it may be of interest to others, I've released the completion plugin on
github: http://github.com/pur
I have a similar problem with deftype/defecord
If I need to mutually defined types...
(declare new-a)
(deftype B
... (new-a)...))
(deftype A)
(defn new-a [] (A.))
