That wording is confusing. I'll fix it.

That wording is correct. Sequences are automatically
iterable even if they don't define __iter__. For example:
>>> class A:
... def __getitem__(self, i):
... if i > 10:
... raise IndexError(i)
... return i * 100
	
>>> list(A())
[0, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000]
If you're curious, the details are in the PyObject_GetIter() function in http://svn.python.org/view/python/branches/release27-maint/Objects/abstract.c?view=markup .
