    This matcher determines if the evaluated object has a property with a given
    name. If no such property is found, ``has_property`` is not satisfied.

    If the property is found, its value is passed 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.

    If the ``match`` argument is not provided, the
    :py:func:`~hamcrest.core.core.isanything.anything` matcher is used so that
    ``has_property`` is satisfied if a matching property is found.

    Examples::

        has_property('name', starts_with('J'))
        has_property('name', 'Jon')
        has_property('name')
