makes possible an idiom for clustering a data series into n-length groups
using ``izip(*[iter(s)]*n)``.
<<<<<<< .working
Note, when :func:`izip` is used with unequal length inputs, subsequent
iteration over the longer iterables cannot reliably be continued after
:func:`izip` terminates. Potentially, up to one entry will be missing from
each of the left-over iterables. This occurs because a value is fetched from
each iterator in- turn, but the process ends when one of the iterators
terminates. This leaves the last fetched values in limbo (they cannot be
returned in a final, incomplete tuple and they are cannot be pushed back into
the iterator for retrieval with ``next(it)``). In general, :func:`izip`
should only be used with unequal length inputs when you don't care about
trailing, unmatched values from the longer iterables.
=======
:func:`izip` should only be used with unequal length inputs when you don't
care about trailing, unmatched values from the longer iterables. If those
values are important, use :func:`izip_longest` instead.
