Yes, rather impressive.  I thought I'd give it something semi-random-ish,
grabbed most recent from my shell history that had a for in it:

(for NS in $(dig +short linuxmafia.com. NS); do for IP in $(dig +short  
"$NS" A "$NS" AAAA); do dig @"$IP" +noall +answer +norecurse  
linuxmafia.com. SOA | sed -e 's/$/ '" @$NS $IP"/; done; done)

Fed it that and it handled it rather impressively, e.g. even going so far
as to not only call out dig, but parse its options and provide details
on what those options do.  Not quite everything, but pretty
impressive.
