    Oooh, I can one-up that hack with this evil from perlrun(1):

    #!/bin/sh -- # -*- perl -*- -W -T
    eval 'exec perl -wS $0 ${1+"$@"}'
    if 0;

    Perl ignores the eval($string) because of the "if 0" in the
    statement. The
    shell sees the statement end at the newline, and executes it faithfully.
    The end result is that the preferred Perl gets the script. I don't know
    Python, so I don't know if such a trick exists there.
