You already mentioned how cleanly event handlers in Ruby/Tk work; you might
also look at what they're doing in Ruby/GTK, which is very nice, e.g.

    button = Gtk::Button.new(...)
    button.signal_connect('clicked') {
        ... this code block is the 'clicked' handler for the button ...
    }

Very easy and unobtrusive. I hope to push FXRuby in this direction in the
near future.

I lost you when you started talking about Java and "interpreted UI
libraries" (i.e. I'm not sure what point you were trying to make) and so I
have no response to that part!

Hope this helps,

Lyle
