darkly remembering a demo which added some demo-syntax to java,
outputting "clean java".
done with a tool packed with javacc called jjtree and a grammar for java.
then there is scheme and python both compiling to java-bytecode.
And Freebell on the FX5 -site. Maybe you can motivate
Frank Sievertsen & RT to allow it / make it usable?

hum. you need javac internal for speed and ClassLoader
to allow for multiple classes of the same name
(like multiple times the same applet loaded).
if i now could remember where i have that prototype stuff,
and how to use/configure.. ;-)

Well, then it needs smarter syntax .I prefer the original. *g*
But if you need to use/learn java, its a funny way.
specially if the composing can be done with
Runtime.exec(uting) rebol :)

Hm, feedback to polish it?
on or off list? the composing part here? ;-)
