As I described earlier, this works fine:

  package Moose::Meta::Method::Accessor::Native::Hash::grep_keys;

  use Moose::Role 1.15;

  with
      'Moose::Meta::Method::Accessor::Native::Array::grep',
      'Moose::Meta::Method::Accessor::Native::Hash',
      ;

  sub _return_value {
      my ($self, $slot_access) = @_;

      return $self->Moose::Meta::Method::Accessor::Native::Array::grep::_return_value("[ keys %{ $slot_access } ]");
  }

  no Moose::Role;

  1;
