:param match: The matcher to satisfy, or an expected value for
        :py:func:`~hamcrest.core.core.isequal.equal_to` matching.

This matcher invokes the :py:func:`len` function on the evaluated object to
    get its length, passing the result to a given matcher for evaluation.

If the ``match`` argument is not a matcher, it is implicitly wrapped in an
    :py:func:`~hamcrest.core.core.isequal.equal_to` matcher to check for
    :equality.

Examples::

has_length(greater_than(6))
        has_length(5)
