yes, but I thought about different inside than you :-)

look at below syntax and try answer how many "1" should be printed out
?

#macro Go(Level)
  #debug "1\n"
  #switch (Level>0?Go(Level-1):0)
    #case(0) 1  #break
  #end
#end

#local A=Go(1);

it produces 98 lines of "1" and error "to many nested symbol tables".
why ?
perhaps it is not the same bug but ...
