I sometimes needed to know if I would say keys %hash in wich order would they come out ? Ofcourse I would like them to come out in the order that I put them when I created the hash. I was disappointed and then I found how hashes work and somehow felt that order in keys of a hash didn't have any reason to exist. But at page 91 in Perl Best Practices , Damian Conway talks about order amongst keys of a hash.

Question: Can one predict this order ? How ?
