I too have wanted more documentation on the CompilerPhase. As more
people ask questions and get answers (like this thread is doing), we
should try to collect the feedback and move it to a wiki page/blog
post.

There is a JIRA open to add examples to groovy, so this will happen in
the next few weeks. I think giving people a small base of working code
and an Ant script is a good start.

I thought there was already a JIRA on this, but I guess I was wrong. I
opened a new one: http://jira.codehaus.org/browse/GROOVY-3601

I checked in the examples that are referenced in the wiki page.
Feedback welcome:
