Hello Experts, I'm trying to share intance via Moose::Role like below

#### Role ####
package MyRole;
use Moose::Role;
has 'nodes' =>
  (
    traits  => ['Hash'],
    is      => 'rw',
    isa     => 'HashRef[Item]',
    handles =>
      {
        set_node    => 'set',
        get_node    => 'get',
        all_nodes   => 'keys',
      }
  );

1;

#### B ####
package BBB;
use Moose;
with 'MyRole';

sub TIEHASH
{
  my $class = shift;
  my $self  = bless {},$class;
  while(my($key,$value) = each(%ENV))
  {
    $self->set_node($key => $value);
  }
  return $self;
}
sub FETCH
{
    my $self = shift;
    my $param = shift;
    return $self->get_node($param);
    return undef;
}
sub STORE
{
  my $self = shift;
  my $key  = shift;
  my $value= shift;

  return unless defined($key);

  return $self->set_node($key => $value);
}
sub DESTORY   { return 1 }
1;
no Moose;
__PACKAGE__->meta->make_immutable;

#### A ####
package A;
use Moose;
use base 'BBB';
with 'MyRole';

sub bind_vars
{
  my $self = shift;
  my $instance = tie(%ENV,'BBB');
  $self->BBB($instance);
  return 1;
}

has 'BBB' =>
  (
    is => 'rw',
  );

1;
no Moose;
__PACKAGE__->meta->make_immutable;
#### main ####
package main;
use base 'A';
my $obj = A->new;
$obj->bind_vars;
# This works , but that's not I expected
print $obj->BBB->get_node('TERM'),"\n";
# I wish to use it in this way
print $obj->get_node('TERM'),"\n";

$ENV{TEST} = 123;
print $obj->BBB->get_node('TEST'),"\n";
print $obj->get_node('TEST'),"\n"

As you can see, this is my requirements:

1.I want to directly call A->get_node(), other than A->BBB->get_node();

2.I don't want to import DESTROY/FETCH,etc into A, I wish to use it as a delegation in somehow.

May I ask if there is any features / easier way can help me directly call B.get_node transparently in A?

Your any kind of help is appreciated!
