  I've attached an example which has been tested on Xandros Linux and Windows XP. Works fine with latest build of source.

I've attached an example of observing the compilation process.
This came out of the discussion here: http://www.nabble.com/Groovy-as-arithmetic-expression-evaluator--to19459935.html

This example code is in /src/examples/groovyShell

The class is called ArithmeticShell. "The arithmetic shell is similar to a GroovyShell in that it can evaluate text as code and return a result. It is not a subclass of GroovyShell because it does not widen the contract of GroovyShell, instead it narrows it. Using one of these shells like a GroovyShell would result in many runtime errors." It should how to observe the compilation process and how to walk the AST.

I did not do a static import on java.lang.Math because it was a hassle to test. I did not extend CodeVisitorSupport for reasons stated in the Javadoc.

It includes a GroovyTestCase but does not include an Ant script to build it.

Perhaps this can help someone.
