Also +1 to containsOnly for this very reason.
In other languages (Python, Ruby, etc) that have an `all` method, they also
have an `any` method, thus maintaining certain consistency.
In the Swift standard library that `any` method is called `contains`, so
`containsOnly` matches nicely that consistency.
