Just to note that it is not possible to mix Macro and Gosub/Return, because 
Gosub is jumping out of the macro. Not sure if this is by design or it is a 
bug, but because of this for me it was necessary to store the macro args to 
channel variables or to rewrite Gosub/Returns as Macros, which in turn may 
lead in depth to be more than 6 :(
