Hi,

After using Jwt from Clojure, I did it with Jruby and discovered that
Jruby has what they call Closure Conversion (http://kenai.com/projects/
jruby/pages/CallingJavaFromJRuby#Closure_conversion ) where a Ruby
block or closure is converted to an appropriate Java interface. From
the wiki: "When calling a method that expects an interface, JRuby
checks if a block is passed and automatically converts the block to an
object implementing the interface".

I found this to be unbelievably easy to use and efficient (for the
developer) as the listener is added this way:
button.clicked.add_listener(self) do
  greeting_.setText(nameEdit_.getText)
end

There's no need for the developer to implement any interface or manage
any proxy object.
I wondered if something similar is possible in Clojure. If not, would
this be considered a valuable addition to Clojure?

Thanks

Raphaƫl
