"""Matches if ``len(item)`` satisfies a given matcher.
: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)
