Hello!
I want to make do a nested hash structure, which seems like that:
my $pname = $self->{db}->{product}->offers->{ $product_id} ->
{name};
This kind of structures can be easily created by TableMap.
Problem: If any of the hash keys are undef, then perl "die"-ing with
an error: Cannot use undef as a HASH reference...
I suggest two kind of solution in the new (perl6) language, because
I think perl5 don't have good solution for that:
1, $__ variable, which is the result of the last operation, e.g:
my $pname = $self->{db} && $__->{product} && $__->offers && $__->{
$product_id } && $__->{name}
2, &&$ operator, which can be used like that:
my $pname = $self->{db &&$ ->{product} &&$ ->offers &&$ -> {
$product_id } &&$ ->{name};
I suggest the second, because it is more straightforward, but the
first is more flexible.

dLux
