Now that we have language injection support for Scala (many thanks for this!), I'm trying to figure out how to actually use it. I've included the .../redist/annotations.jar file as a dependency and can import and apply the annotations (to val definitions and formal parameters), but they seem to have no effect. I created deliberately erroneous regular expression and XPath literals, but there was no feedback to that effect.
Is the language injection support fully operational? If so, what's the right way to use it? Is there any kind of documentation or notes on how to use this feature in Scala code?
