You only need a shebang on under Unix, where you invoke the file by name from
the command line, thus:

stephen$ myscript.pl

If you pass the name as an argument to perl , you don't need shebang:

stephen$ perl myscript.pl

And Windows uses the extension to figure it out.

c:> myscript.pl

(but no .pl, no luck!).

Shebang lines are a nice bit of hackery to let Unix shells know what interpreter
to use on executable text files, so the above is also valid for python, tcl,
bash, etc.
