First we can use Data::Denter which sorts the keys. Now it's output is not
suitable for strightforward require(), so the manpage suggests:
For example if you wanted to set up a config file with 3
options, you might choose a format like this:
option1 => value1
option2 => value2
option3 => @
sub-value-a
sub-value-b
To read this into Perl you could say:
use Data::Dumper;
use Data::Denter;
$Data::Denter::HashMode = 1;
open CONFIG, 'config' or die $!;
my %config = Undent join '', <CONFIG>;
print Dumper \%config;
So we store the keys sorted and easily maintainable. And only need to
preprocess with Data::Dumper to deserialize.
Alternatively, since we know what data we want to dump (only arrays,
hashes and scalars), a simple function which generates the output like
Dumper but sorted will do.

ok
