I think the first challenge is to discover recursion. I was thinking about discovering recursion when a macro call is being executed.
When the node tree is rendered lets say at some point it reaches a macro. At this point, if I can keep track of whether children of this node calls the same macro again before the original call finishes, I will be able to discover recursion. I have tried this method in several places i.e. ASTDirectve.render and VelocimacroProxy.render by keeping track of the state in ASTDirective class and VelocimacroProxy class. First time render method is called by a Macro invocation I kept the status in a private variable and when the next call occurs I checked this variable to see weather the previous macro call is completed. But then I realized that objects from these classes are created every time a call occurs to a macro. So I cannot keep track of the macro calling state in these classes.
