Self-referential proxies

[Kevin]

Hello,

I had some difficulty writing the following java code in Clojure:

Runnable runnable = new Runnable() {
public void run() {
animate();
display.timerExec(TIMER_INTERVAL, this);
}
};
display.timerExec(TIMER_INTERVAL, runnable);


For the moment I have worked around the 'this' reference using refs.
Is there a cleaner way of doing this? If not a 'this' function/symbol
might be useful for the proxy macro.

This is roughly how I wrote it:

(let [runnable (ref nil)] (dosync (ref-set runnable (proxy [Runnable]
[] (run [] (animate) (dosync ... @runnable ...

Clojure functions implement Runnable, so you ought to be able to do
something like:

(defn my-run []
(animate)
(.timerExec display *timer-interval* my-run))
(.timerExec display *timer-interval* my-run)

That's untested. Good luck. :-)

Thanks, that's handy to know and a lot cleaner.
