I mean code duplication on the user side. A function that operates on every
iterator or sequence type is far more useful than a protocol that more
often than not wouldn't be implemented.

Because it would have to begin and end with two underscores (thats the
naming convention for special methods), and astring.__len__() already does
what you want. But I think it is mostly for historical reasons.
