One useful application of the second form of :func:`iter` is to read lines of
a file until a certain line is reached. The following example reads a file

if it contains exactly one item. The *buffer* must contain at least the amount

For example::

Note that a single name can be bound to multiple objects. If the result
is ``True``, the name may also be bound to other objects, like an int or
list, that does not introduce a new namespace.
