I see. Actually my idea was to populate the nodeMetaData map and access it via `class.metaClass.classNode.nodeMetaData`, but it seems not possible. 

But the the use of annotation sounds a nice idea. 

Thanks.

Unless you have an AST xform that takes that node metadata and injects it into bytecode in a way that it's available at runtime (say, within an annotation), no, it's not possible.

Dear all, 

Is it possible to inject some values in a nodeMetaData during AST transformation and access such values at runtime  ?
