DATA does indeed "point to" the input file, right after the __END__. You can 
verify this for example by calling DATA.rewind. After that, you can read the 
text before the __END__.

Why do you need $. to start from 0 when reading from DATA? What is it that 
you're trying to do?

Personally, I think it shouldn't be allowed to change the $. variable at all. 
YMMV of course.
