Hello MONKS,

Question: I have an abundance of equal size arrays that need to be associated, having understood 1:1 mapping, for example: 

my %myhash = map { $array1[$_] => $array2[$_] } 0 .. $#array1;

Consistent with the above example I would like to use $array1 as a hash key but inside of a more complex Hash of Hashes which would associate $array3, $array4, $array5 ... using the array name as the subkey for the nested hash.

Possibly: 

my %HoH = map { $array1[$_] => “array2” => $array2[$_] } 0 .. $#array1
+;
%HoH = map { $array1[$_] => “array3” => $array3[$_] } 0 .. $#array1;
%HoH = map { $array1[$_] => “array4” => $array4[$_] } 0 .. $#array1;
%HoH = map { $array1[$_] => “array5” => $array5[$_] } 0 .. $#array1;

[download]
etc. etc. until all the arrays have been associated within the HoH.

I want the final HoH to work something like this: 

Foreach @array1 {
   print $HoH{$array1[$_]}{array5} # array5 associated with array1 
   print $HoH{$array1[$_]}{array4} # array4 associated with array1
   print $HoH{$array1[$_]}{array3} # array3 associated with array1
  # etc. etc.
}

Is the above code a proficient way of associating all arrays with the array1 keys within the same data structure?

All advice is always greatly appreciated!

Thanks.
