:param value_match: The matcher to satisfy for the value, or an expected
value for :py:func:`~hamcrest.core.core.isequal.equal_to` matching.
This matcher iterates the evaluated dictionary, searching for any key-value
entry whose value satisfies the given matcher. If a matching entry is
found, ``has_value`` is satisfied.
Any 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_value(equal_to('bar'))
has_value('bar')
