Do you have to write obfu like that out by yourself or is there something that does it for you? I've got an idea for a good obfu but I don't know how to go about making it...
There's an article at IBM about japh-writing which isn't bad. This one just grew out of some experimenting with autoloading, how Perl knowing something is a sub affects the parse, etc. First I wondered what Perl would try to do with the bare "just another perl hacker" in the last line, i.e. what would get sent to AUTOLOAD. Then when I found out, the rest was my trying to hide the autoload function.
