What I'm expecting, is that I get an event as soon as I move the mouse
over a link, and print "Spam and eggs!" is displayed. But I don't see any
output, so I'm concluding that, either I have not implemented the correct
function or there's something fishy going on. I hope it's the former
though.

I've implemented it in JAVA as well as in Piccola, a research scripting
lanugage at our University. What we are currently missing, is the
possibility to implement interfaces on the fly, as they require some
compilation. Therefore, I'm currently looking at your implementation for
inspiration.

Any hint, where to look especially is warmly welcomed.
