Is the following possible with Moose?

I have a class which has an object of another class as an attribute:

package My::ABC

has 'db_accessor' => (
    is  => 'rw',
    isa => 'My::DEF',
);

Inside this DEF class there are multiple methods which are called from ABC. They throw exceptions on errors (die). However, in this special case of class ABC I don't want the script to die, I want it to continue. At the same time I don't want to put an "eval" around each method call of "db_accessor".

I already tried to use the "around" modifier of Moose, but that seems to only work for the constructor, not for the method calls on "db_accessor". I tried it like this:

around 'db_accessor => sub {
    my $orig = shift;
    my $self = shift;
    my $out;
    eval { $out = $self->$orig(@_) };
    if ($@) {
        $self->warn("Access failed with: [$@]");
    } else {
        return $out;
    }
};

However, this doesn't work. An access in this form still causes the script to die: $self->db_accessor->methodA();

Any idea how to solve this with Moose? Thanks in advance!
