  • The slides showing how awful it can be to have to manage your own inside-out objects are not intended to be a robust explanation of how to force yourself to suffer through it, but an overview of the various levels of annoyance that heap up without fieldhashes.<br /><br/>

  • Errata: (?)

    Slide 88:
    =======
    Unless you meant to leave $id as an unused variable to resolve in later slides, I'd suggest this change....

    s( $site{$self} )
    ( $site{$id} )gx

    Slide 89:
    =======
    Ditto

    Also, make these changes
    $new should be $new_id
    $old should be $old_id<br /><br/>
