Use a tied hash.

package DefaultHash; sub TIEHASH { my $class = shift; my $default = shift; my $self; $self->{_DEFAULT} = $default; $self->{_HASH} = {}; return bless $self, $class; } sub FETCH { my $self = shift; my $key = shift; return exists $self->{_HASH}{$key} ? $self->{_HASH}{$key} : $self->{_DEFAULT} } sub EXISTS { my $self = shift; my $key = shift; return exists $self->{_HASH}{$key}; } sub FIRSTKEY { my $self = shift; my $foo = keys %{$self->{_HASH}}; # Reset each return each %{$self->{_HASH}}; } sub NEXTKEY { my $self = shift; return each %{$self->{_HASH}}; } sub CLEAR { my $self = shift; $self->{_HASH} = {}; } sub DELETE { my $self = shift; my $key = shift; return delete $self->{_HASH}{$key}; } sub STORE { my $self = shift; my $key = shift; my $value = shift; $self->{_HASH}{$key} = $value; } package main; tie( my %hash, 'DefaultHash', 'a default value' ); %hash = ( a => 1, b => 2, c => 3 ); print "$_ => $hash{$_}\n" for qw(a b c d);
