Perl Style: 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";
