## Seen

    $obj->Seen([hashref])

Queries or adds to the internal table of references that have been encountered. The references aren't dumped, but their names are inserted when they are encountered subsequently. With no argument, returns the "seen" list of `name => value` pairs, in array context. Otherwise, returns the object itself.
