CPython is full of defensive code protecting against malicious crap.
That's why it rarely crashes ;-)
def __lt__(self, other):
return self.size < other.size
Looks harmless? Can't tell! For all we know, there are proxy
objects, and other.__getattr__ invokes some elaborate library to open
a socket in a new thread to fetch the value of `size` over a network.
