Each of the three functions entry in perlfunc now has the following paragraph: +Hash entries are returned in an apparently random order. The actual random +order is specific to a given hash; the exact same series of operations +on two hashes may result in a different order for each hash. Any insertion +into the hash may change the order, as will any deletion, with the exception +that the most recent key returned by C<each> or C<keys> may be deleted +without changing the order. So long as a given hash is unmodified you may +rely on C<keys>, C<values> and C<each> to repeatedly return the same order +as each other. See L<perlsec/"Algorithmic Complexity Attacks"> for +details on why hash order is randomized. Aside from the guarantees +provided here the exact details of Perl's hash algorithm and the hash +traversal order are subject to change in any release of Perl And damn, I now notice a missing full stop on the last line. /grrr I'll postpone fixing it for awhile to see if there are any further changes recommended by the list.
