Getting last valid index from a particular list in a @LoL

willick has asked for the wisdom of the Perl Monks concerning the following question:

Say you have a list of lists (@LoL) that contains 5 lists and the third list contains 6 entries. Can you not get the last valid index value easily from that third list if you didn't know what it was? I was thinking that something like the following would work...

my $last_valid_index_val_for_list3 = $#LoL[3];
