That is very cool.  I knew about the deparse module I just never had a use case.

Subject: [PLUG] perl -MO=Deparse

I don't know how I've missed this, but I have.  I love Perl one-liners,
but I never knew you could "deparse" them!

-----
$ perl -MO=Deparse -a -F/:/ -ne 'print "$F[2]\t$F[0]\t$F[6]";'
/etc/passwd | head -n4
-e syntax OK
LINE: while (defined($_ = <ARGV>)) {
    our(@F) = split(/:/, $_, 0);
    print "$F[2]\t$F[0]\t$F[6]";
}

$ perl -a -F/:/ -ne 'print "$F[2]\t$F[0]\t$F[6]";' /etc/passwd | head -n4
0	root	/bin/bash
1	daemon	/usr/sbin/nologin
2	bin	/usr/sbin/nologin
3	sys	/usr/sbin/nologin
