Actuaqlly, it will work the way he has it. The anonymous hash is
auto-vivified on first assignment:
Greetings! E:\d_drive\perlStuff>perl -w
my $self;
$self->{'up'} = 'high';
$self->{'down'} = 'Hi';
print "$_: $self->{$_}\n" foreach keys %$self;
^Z
down: Hi
up: high
I do agree, though, that assigning the empty hash reference at declaration
is more self-commenting.
