in reply to Having a problem creating a hash with the map function

If you wanted to get fancy and cryptic, you could create your "goal" hash by:

my %Belfast_car_dealer_hash = map{$_=>1} @{$car_city_dealer_aoa[0]} [1..$#{$car_city_dealer_ao +a[0]}];
but I would not write code like that without an explanation:
It uses an array-slice of @{ $car_city_dealer_aoa[0] }, skipping the first (0) element, and mapping the rest.
