Eric Wieser <wieser.eric+py...@gmail.com> added the comment:
What I think I find surprising is that I'd expect the sequence protocol to be
defined by `__getitem__` and `__len__`, and for `__iter__` to be inferred as:
def __iter__(self):
for i in range(len(self)):
yield self[i]
But in reality it seems it is inferred only from `__getitem__`, as:
def __iter__(self):
i = 0
while True:
try:
yield self[i]
except IndexError:
return
i += 1
