Using A Hash Instead of $$name

• Using a variable to contain the name of another variable always suggests that perhaps someone doesn't understand hashes very well. While you could write this:

      $name = "fred";
      $$name{WIFE} = "wilma";     # set %fred
  
      $name = "barney";           # set %barney
      $$name{WIFE} = "betty";
  

• Better to write:

      $folks{"fred"}  {WIFE} = "wilma";
      $folks{"barney"}{WIFE} = "betty";
