And even using a stack suffers from the flaw that any sort
of refactoring that puts a loop around a portion of the code
means search through the entire section and increasing the
index of any reference to a loop outside the new one, while
not increasing the index of any reference to a loop within
the new one. That's a good source of subtle errors there.
