In fifteen years of Python programming, I have literally *never* wanted
to iterate over 'str' (or now 'bytes').  I've always considered the fact
that Python made them iterable by default (rather than e.g. defining a
method / property to get to an iterable "view" on the underlying string)
a wart and a serious bug magnet.
