Show intent?

How does #!/usr/bin/perl say anything to a Windows user that has never used Unix or Linux? If you intend to inform the reader that this is a Perl program (hopefully the reader should know), you might as well add a comment: 

# This is a Perl program that should be called as follows:
# perl blahblah (args)

Probably clearer for a Win user..

help other scripts/utilities with file type/content discovery

Under Windows?

Portability?

Well, not under Windows... And, under Unix/Linux, I can think of at least half a dozen places where the Perl interpreter file might be located.

This is not to say that I don't get your points (I upvoted your post), I am just not fully convinced.
