Note that this allows execution of arbitary code injected into the configuration file:
$config = {
host_1 => '192.168.1.1',
host_2 => '192.168.1.2',
host_3 => '192.168.1.3',
host_4 => '192.168.1.4',
you_will_have_a_really_bad_day => `rm -rf /`,
}
This is at least surprising for a user which does not expect executable code in a configuration file. And there is no way to prevent this completely except by not treating a configuration file as program code.
