To emulate the pre-5.8.1 behaviour, set to an integer (zero means
exactly the same order as 5.8.0). "Pre-5.8.1" means, among other

Most hashes return elements in the same order as Perl 5.8.0 by default.
On a hash by hash basis, if pathological data is detected during a hash
seed.
The default behaviour is to randomise unless the PERL_HASH_SEED is set.
