i am reading in the "Perl Cookbook" at the bottom of page 449. i am confused about the use of the values and keys functions with respect to the order in which those results are returned.

i thought the ordering of keys/values are or will be random, i.e. the values function gathers the values and returns them in random order; then the keys function gathers the keys and returns them in random order.

my understanding is that the order of keys and values being returned is affected by insertion order. i also thought that soon if not already the order returned is further randomized for some sort of security thing.

if i understand the following code, the keys function and values function will have to operate on the hash at the same time. will the following really work? 

my %extra = @_;
@${self{keys %extra} = values %extra;

thanks.
