      py/objexcept: Allow clearing traceback with 'exc.__traceback__ = None'. · c3d96d38
      Paul Sokolovsky authored
      We allow 'exc.__traceback__ = None' assignment as a low-level optimization
      of pre-allocating exception instance and raising it repeatedly - this
      avoids memory allocation during raise. However, uPy will keep adding
      traceback entries to such exception instance, so before throwing it,
      traceback should be cleared like above.
      'exc.__traceback__ = None' syntax is CPython compatible. However, unlike
      it, reading that attribute or setting it to any other value is not
      supported (and not intended to be supported, again, the only reason for
      adding this feature is to allow zero-memalloc exception raising).
