My guess is that it isn't possible (or a really good idea) for the simple reason that Values can be called by more than one Name. There is *not* a 1 to 1 relationship between them. At least in the untied world, it would be quite cumbersome to make sure Values always new exactly what Names were refering to them. Consider the following code:

#!/usr/bin/perl -wT
use strict;

my $x = {name => 'x', value => 123};
my $y = $x;
$y->{name} = 'y';
$y->{value} = 321;

print "X: $x->{name} => $x->{value}\n";
print "Y: $y->{name} => $y->{value}\n";

=output
X: y => 321
Y: y => 321

Here we have the *names* 'x' and 'y' pointing to the same value.. It doesn't make sense in this instance for the value to know what its name is, because it has more than one (could have used an anon hash, in which case it would have no Name at all).

In general I think its a bad idea to attempt to replicate the name of the variable in the contents of the variable. However, I haven't done much Tie:: development (used them a bunch, but haven't spent much time under the hood) so take my advice in the more general sense.
