Is there a way to assert that a collection contains a single element that satisfies some assertions (rather than a predicate returning boolean?)

[phldavies]

i.e. something like

warnings.shouldHaveSingleElementSatisfying {
    message shouldContainIgnoringCase "cheese"
    code shouldBeGreaterThan 100            
}

myList.forOne { }
