in reply to __DATA__ read/write as configuration file

How do I do this? read __DATA__ then seek to 0 then write over it?
Yes, just open up the current script and write to it like you would any other file e.g
use Fatal qw/ open seek /; open(my $d => '+<', $0); seek $d => 0, 2; print $d @ARGV; __DATA__ foo bar
This will append @ARGV to the __DATA__ section of the currently executing script. Of course modify the seek as you see fit and if you're going to completely overwrite it then remember it's position with a quick tell.
