Don't know about supercollider3

I tested choco with groovy, a nice language.
But Groovy only works with java.
Ruby is another nice language (true object, ...) from witch groovy
is derived.
But ruby (as a C interpreter) come with much more libraries
and is strongly supported by sun in its JRuby version
(JRuby-1.0.0 has just come out (10 june !)

You can get it at :
	http://dist.codehaus.org/jruby/

Here is a verbose sample of a MagiScare un JRuby
(It works on
     - Mac-osx and linux
     - with jruby-1.0
     - with choco-cvs-20070125.jar

The following example show how Ruby can add a method
to an existing choco class.
Operator overloading could also be usefull for specifing
constraint, but choco design seems not be very adapded
for this purpose (if IntExp interface provide
     IntExp eq(IntExp),
     ...
Then ruby would just had to add "=3D=3D" method to
the IntExp class, or somethong like that...)
