Ah, tailor-made for the little-used `-x' option for perl.
Observe:
[~] $ cat test.sh
#!/bin/sh
echo "In shell part"
FOO=`/usr/bin/perl -x $0`
echo <<'__END__' > /dev/null
#!/usr/bin/perl -wl
print "In perl";
__END__
echo "Perl said: $FOO"
echo "Back in shell"
[~] $ sh test.sh
In shell part
Perl said: In perl
Back in shell
[~] $
Ain't that fun? See perlrun for details on `-x'.
