I don't think so, but perhaps I misunderstood the proposal.  I thought
it would just rely on someone defining a String Interface as the union
of ``str.lower``, ``str.split``, etc.  Then to figure out what to do
with your ``string_or_list`` argument, you'd test it against this
String Interface. You could then freely make calls like ``s.lower()``,
knowing that they were calling the equivalent of ``str.lower()``.
