I think we're already there. In your example above, $date would be an
overloaded "object". For example:
$date = localtime(); # date is an object that knows how to:
print scalar $date; # output itself in scalar context
$year = $date->{year}; # be accessed as a method
We just need a hook (think "tie") to make $date morph as needed. Of
course, we'd probably need to expand all of the special tie methods
(FETCH, STORE, etc.)
