These are a two dimensional array and a one dimensional array, not 3d
and 2d. What you want is called flattening. you can flatten easily by
referencing each element of @AoA. I would use a map to do this:
my @array = map { @$_ } @AoA;
You could also use a for loop:
my @array;
for my $arrayref (@AoA) {
push @array, @$arrayref;
}
