As mentioned above, I don't think it's possible. The solution mentioned by Eily; to avoid people using your tie packages directly, and provide them with a wrapper sub which captures the name of the tied variable and passes it as an argument to tie is probably the best thing to do.

Here's about as elegant as I could make it, but this solution is limited to package variables (i.e. our, not my)...

#!/usr/bin/env perl

use v5.14;

package MyTie {
    use Attribute::Handlers;
    use Tie::Hash ();
    use base 'Tie::StdHash';
    sub TIEHASH {
        my $class = shift;
        warn "Tied hash: @_!!!\n";
        return $class->SUPER::TIEHASH(@_);
    }
    sub UNIVERSAL::MyTie :ATTR(HASH) {
        (my $name = ref $_[1] ? *{$_[1]} : $_[1]) =~ s/^\*?/%/;
        tie %{$_[2]}, 'MyTie', $name;
    }
    BEGIN { $INC{'MyTie.pm'} = __FILE__ };
}


use MyTie;
our %monkey :MyTie;
my %gorilla :MyTie;
