One certainly hopes they haven't broken one of the few guarantees given in the POD:

keys HASH

Returns a list consisting of all the keys of the named hash. (In scalar context, returns the number of keys.)

The keys are returned in an apparently random order. The actual random order is subject to change in future versions of perl, but it is guaranteed to be the same order as either the values or each function produces (given that the hash has not been modified). Since Perl 5.8.1 the ordering is different even between different runs of Perl for security reasons (see Algorithmic Complexity Attacks in the perlsec manpage).

Then again, it would have been useful to jave been told how this new randomisation varies from that which has been in place since 5.8.1?

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
