compile time annotation processing tool for Scala?

The Scala compiler does not support java Annotation Processors.It would need to map scala declarations to the interfaces incom.sun.mirror.declarations somehow,http://java.sun.com/j2se/1.5.0/docs/guide/apt/mirror/com/sun/mirror/declaration/package-summary.html
I don't think anybody is working on that.

If you interface to it from java you run apt or "javac -processor".
How would you process such annotations in scala code.
It seems that this would be a recurring problem.
I would do this by writing a compiler plugin that can
apply a AnnotationProcessor & AnnotationProcessorFactory
to annotations in Scala sources.
Has anybody done this? Or is there a better way?

Hi Lukas,

Is this also true of javax.annotation.processing.Processor?

thanks
Daniel

I don't know, I'm actually completely unfamiliar with Java'sannotation processors..
