[issue8376] Tutorial offers dangerous advice about iterators: “__iter__() can just return self”

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <amauryfa at gmail.com> added the comment:

Why do you call this "dangerous"? because the object can be iterated only once? But reversed() does the same thing.
And all iterators objects must also implement the __iter__ method that return themselves, otherwise they cannot be used in a for loop.
Better start with such an object.
