That's fine. Look at it this way: $trunk{$_} is a reference to
an anonymous hash containing some data.
delete $trunk{$_} removes the entry from %trunk. Since it was
a reference to an anonymous hash, that hash's reference count
is decremented. Assuming there are no other references to that
hash (i.e. you didn't make a copy earlier like $foo = $trunk{$_}),
Perl will notice that and will release the anonymous hash.
