Okay, so I left off the "Enjoy!" and so ctweten's has gotten more votes than mine. ;)

This discussion has been so short and to the point, I thought I'd add a bit...

I dislike having to use the %{...} syntax as it is hard to read. One solution is: 

    $ref= $obj->{param};
    for(  keys %$ref  ) {
        Mung( $ref->{$_} );
    }

But what we really need is a post-fix operator that give you the whole hash (or array, or scalar, etc.) from a reference: 
    my @keys= keys $obj->{param}->%;

This was proposed on perl5-porters a while back but noone has submitted a patch (as far as I know) to implement it. So here is your chance to become famous. Go to the perl5-porters archive and read up on the proposal and you've got a great project for learning Perl guts.
