"just testing"?
exists() just doesn't shortcut.
So to test $var->{foo}{bar}[5]
you just need to have $var->{foo}{bar}, etc.
Just Google on autovivication. Just some examples:
http://en.wikipedia.org/wiki/Autovivification
http://www.sysarch.com/Perl/autoviv.txt
Or just step through your code with perl -d.
