        .differ('a').instance_of(str).expect(lambda x: x, 1)
>>> print(condition.result(), condition.success, condition.failures, sep='\n')
False
[('be', 2), ('equal', 0.0), ('differ', 'a'), ('instance_of', 'str'), ('expect', ('<lambda>', 1))]
[('be', 2), ('equal', 0.0), ('instance_of', 'str')]
>>> condition = Condition([1,2,3]).contain(1).have('append').hold(3)
