Not quite. In my config language, "ignored" means ignored. There was no 
way of accessing the rest of the file, short of guessing the file name, 
opening it and reading it as text.

In Perl, the __END__ and __DATA__ keywords mark the end of the Perl 
program, and leave the rest of the document visible to the caller via a 
special file handle:

You know, I actually kinda like that...
