Proposal: add .Panic() alongside .Return(...) for interrupting a test

[unkeep]

It would be useful for testing expectations which do not return an error or the error does not interrupt a flow.

example code:

func foo(dep Dependency) {
    dep.doSmth1(...)
    dep.doSmth2(...)
}

example test:

It("should doSmth1", func(){
    depMock.Expect(...).Panic()
    Ω(func(){foo(depMock)}).Should(Panic())
})

Of course the same could be done by adding panic() to the end of Inspect func, but the proposed way is more natural and shorter

[hexdigest]

Hey, you can achieve the same using Set:

It("should doSmth1", func(){
    depMock.Set(func(...) {
       panic("is good for you")
    })
    Ω(func(){foo(depMock)}).Should(Panic())
})

I don't think it deserves a special helper.
