ances of zero-based,
integer-indexed collections, such as <code>Array</code> and <code>ContiguousArray</code>. For
other collections the counters may be out of range or of the wrong type
to use as an index. To iterate over the elements of a collection with its
indices, use the <code>zip(_:_:)</code> function.</p>

<p>This example iterates over the indices and elements of a set, building a
list of indices of names with five or fewer letters.</p>
