Descrizione
If a run futurize on python 2 code containing a subclass of the built in dict, e.g.
class A(dict):
__nonzero__(self):
return False
it is translated to
class A(dict):
__bool__(self):
return False
However, the __bool__ method is not called in python 2. Seems some other kind of trickery is needed.
For now I'm working around the issue by doing
class A(dict):
__bool__(self):
return False
if sys.version_info[0] == 2:
__nonzero__ = __bool__
