At first, I was thinking I could support "perl -p" (not in the #! line) giving a helpful message since it is expecting both its script and its input from STDIN. But I immediately thought of using a "TTY" as STDIN such that you can have two "ends of file" on the one STDIN: 

shell> stty eof ^Z
shell> perl -p >>notes
BEGIN { print ''.localtime(),$/ } $_= "$.: $_"
CTRL-Z
Here are my notes for today.
I should really make this a real script.
CTRL-Z

But then I realized you can use __END__ to do this trick anywhere: 

shell> cat script
$_= "$.: $_";
__END__
Testing
this.
shell> perl -p <script
1: Testing
2: this.

Granted, I haven't come up with a great use of this feature, but I'm reluctant to promote disabling it merely based on my lack of imagination. (:
