incorrect results? by whose definition are the results incorrect? you
didn't read the docs to understand autoviv and assumed incorrect
behavior. i lay that on you and not perl.

the real moral is you haven't learned yet how to work with perl data
structures. needing to print low level entries is very unusual. that
leads me to suspect the quality of your structure's design. i have done
many deep structures and never have come across this need. usually
something at a higher level can be done so you don't need to directly
access missing elements and thereby cause autoviv to happen.
until you learn more about perl and its data structures you will be
doomed to this poor style of design and coding.
and read my article already. it was written specifically for you.
