Highlights
^^^^^^^^^^
* Now another matchers can be passed as ``have_been_called_with`` arguments::
my_spy = Spy()
my_spy.method(1)
expect(my_spy.method).to(have_been_called_with(an(int)))
* Added the ``anything`` matcher::
expect(my_spy.method).to(have_been_called_with(anything))
* Added the ``any_arg`` special matcher::
expect(my_spy.method).to(have_been_called_with(1, any_arg))
