Composition of an Array of Hashes

You can create an array of anonymous hashes as follows:

@AoH = (
    {
       husband  => "barney",
       wife     => "betty",
       son      => "bamm bamm",
    },
    {
       husband => "george",
       wife    => "jane",
       son     => "elroy",
    },
    {
       husband => "homer",
       wife    => "marge",
       son     => "bart",
    },
  );

To add another hash to the array, you can simply say:

push @AoH, { husband => "fred", wife => "wilma", daughter => "pebbles" };
