After studying Mark's patch and the rest of the code, I understand the for loop oddity.

The else block of the for loop comes after the 
compiler_pop_fblock(c, FOR_LOOP, start);

So you can do this all day and it won't complain:

for x in '1': pass
else:
 for x in '2': pass
 else:
  for x in '3': pass
  else:
   for x in '4': pass
   else:
    for x in '5': pass
    else:
     for x in '6': pass
     else:
      for x in '7': pass
      else:
       for x in '8': pass
       else:
        for x in '9': pass
        else:
         for x in '10': pass
         else:
          for x in '11': pass
          else:
           for x in '12': pass
           else:
            for x in '13': pass
            else:
             for x in '14': pass
             else:
              for x in '15': pass
              else:
               for x in '16': pass
               else:
                for x in '17': pass
                else:
                 for x in '18': pass
                 else:
                  for x in '19': pass
                  else:
                   for x in '20': pass
                   else:
                    for x in '21': pass
                    else:
                     for x in '22': pass
                     else:
                      for x in '23': pass
                      else:
                       for x in '24': pass
                       else:
                        for x in '25': pass
                        else:
                         for x in '26': pass
                         else:
                          for x in '27': pass
                          else:
                           for x in '28': pass
                           else:
                            for x in '29': pass



I guess the same goes for while loops, and the else of a try-except.


Since If blocks were deliberately left out of this game, I'm assuming that this "static nesting" is actually number of frames, rather than true static nesting. If that is the case then there is no issue here and we can close this ticket.

But if this is something to be fixed, then I am happy to make a patch along the lines of Mark's (which I partially already have).
