    """Matches if object has a property with a given name whose value satisfies
    a given matcher.

:param name: The name of the property.
    :param match: Optional matcher to satisfy.

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')

:param matcher_dict: A dictionary mapping keys to associated value matchers,
        or to expected values for
        :py:func:`~hamcrest.core.core.isequal.equal_to` matching.

Note that the keys must be actual keys, not matchers. Any value argument
    that is not a matcher is implicitly wrapped in an
    :py:func:`~hamcrest.core.core.isequal.equal_to` matcher to check for
    equality.

Examples::

has_properties({'foo':equal_to(1), 'bar':equal_to(2)})
        has_properties({'foo':1, 'bar':2})

``has_properties`` also accepts a list of keyword arguments:

.. function:: has_properties(keyword1=value_matcher1[, keyword2=value_matcher2[, ...]])

:param keyword1: A keyword to look up.
    :param valueMatcher1: The matcher to satisfy for the value, or an expected
        value for :py:func:`~hamcrest.core.core.isequal.equal_to` matching.

Examples::

has_properties(foo=equal_to(1), bar=equal_to(2))
        has_properties(foo=1, bar=2)

Finally, ``has_properties`` also accepts a list of alternating keys and their
    value matchers:

.. function:: has_properties(key1, value_matcher1[, ...])

:param key1: A key (not a matcher) to look up.
    :param valueMatcher1: The matcher to satisfy for the value, or an expected
        value for :py:func:`~hamcrest.core.core.isequal.equal_to` matching.

Examples::

has_properties('foo', equal_to(1), 'bar', equal_to(2))
