The |bar.__codec__ = 'foo'| is especially weird; it doesn't raise an exception
but feels like it should. Couldn't figure
out how to get that to happen [...]
The issue here is that, similarly to __getattribute__, __setattr__ is /always/ called; while object.__setattr__ is smart
enough to deal with descriptors such as @property, most other __setattr__s remain blissfully unaware.
So the standard __setattr__ dance is something like:
def __setattr__(self, name, value):
if name in ('things', 'I', "don't", 'want', 'to', 'deal', 'with'):
return super(MyClass, self).__setattr__(name, value)
# deal with the stuff I do care about here
