I see EvaluatorAdaptor is fundamental, but it should be possible to get at least the line number of a node. E.g.:
// with is on 2:0 (line 2, column 1)
Programatically I don't have min idea in asc.parser.Parser... Node.java has no line thing... X_X
I did read the classes you said, but I didn't find anything. But there should be a way to handle lines, as mxmlc is able to get line numbers and etc., right?
