in thread Hash order randomization is coming, are you ready?
Yes indeed. This cannot change. And is guaranteed by the nature of the how keys() and values() are implemented in native hashes (non-magical). Basically they are both achieved by walking the bucket array from left to right and within a bucket from top to bottom. Since they both do the same data structure walk they both return the same results. However note this is true only of a /given/ hash. You can't assume that one hashes keys() will match another's values() even if they contain the same list of keys().
