That said, I think the /usr/bin/env trick is stupid too. It may be more
portable for various Linux distributions, but if you want _true_
portability, you use /bin/sh, and you do something like

#!/bin/sh
exec perl perlscript.pl "$@"

if 0;

exec may fail.

#!/bin/sh
exec perl -x $0 ${1+"$@"} || exit 127
#!perl

You don't really want Perl to get itself into an exec loop.

This would _not_ be "perlscript.pl" itself. This is the shell-script, and
it's not called ".pl".

In this thread, it originally was.
