Actually,
! exists %poeple ->{$first}->{$Last}-{$MI}
is not valid syntax. I assume you meant
!exists $poeple{$first}->{$Last}->{$MI}
which can be shortened to
!exists $poeple{$first}{$Last}{$MI}
This expression will auto-vivify $people{$first} and
$people{$first}{$Last} if they don't already exist
(but NOT $poeple{$first}{$Last}{$MI}).
Is this really your data model? Why all the nested
levels of hashes?
