Moreover inside of the arguments of the macro the counter is temporarily decreased as those cases do not count as a loop. Any self reference is rendered as "Self reference: foo". Maybe not the most elegant solution, but it does the job until another clean implementation of the macros is available.What do you think Andre'? Abdel.
I was thinking about tracking the dependency graph of used macros in a macro definition and look for loops. Then return a harmless MathMacro with some error string in that case. But that would probably be much more complicated. I don't see it as a long term fix anyway as the macros need a proper reimplementation.
