Yes, this is possible.
Tie::SecureHash is an example of
a class that does this.
In order to get the object and tied hash interface all at once,
though, you have to be slightly tricky, and you need to create
your object using the object constructor interface, not the tie
interface:
sub new {
my $class = shift;
tie my %self, $class;
bless \%self, $class;
}
That returns a reference to the tied hash, which is also an
object that is blessed into
$class, which means that
you can either use it as a tied hash, *or* call methods on it.
(NOTE: In the above example, the object is blessed into the tie
class, but this is not required.)
