In trying out some Groovy 2.5 examples, I noticed that the Groovy Web Console at https://groovyconsole.appspot.com/ is running Groovy 2.4.4 (confirmed by 'GroovySystem.version' property). Could this deployment be updated to Groovy 2.5.0? Is there a way to indicate and possibly select other Groovy versions for this app?
Also, the Groovy 2.5.0 documentation (http://docs.groovy-lang.org/docs/groovy-2.5.0/html/documentation/) has no section for the new @NamedVariant AST transform. There are a few variations of this transform and I did not find much help in the Javadocs or release notes beyond the most basic case.
