Ah, thanks. I have a __getitem__ method, but it currently doesn't raise
IndexError. (I'm indexing into a ring buffer, and the usage of the class
pretty much precludes index

You can either use __ite

What method(s) does a class have to support to properly emulate a container
which supports turning it into a list? For example:
class Foo:
pass
f = Foo()
print list(f)
Is it just __iter__() and next()? (I'm still using 2.4 and 2.7.)
