Dearest Monks, I use Math::Vector::Real with XS (I'll refer to it as MVR) as a core dependency of my molecular object system. MVR exports the function V that creates the MVR object (a vector of numbers that has useful methods). e.g. atomic coordinates are MVR objects. My classes use the methods of MVR within a Role. Instances of my classes use the V function: 
my $atom = Atom->new(Z=> 80, coords => [V(0,0,0), V(1,1,1), V(2,2,2)])
+;

creates a mercury atom with three MVR coordinates. The coords attribute is an ArrayRef-MVR with Array traits; I push_coords, get_coords, set_coords etc. I have two goals: 1. be able to use MVR's V function without having to add use Math::Vector::Real to every script. 2. be able to add MooseX::Storage capabilities for MVR to my classes. So I'm trying to subclass MVR: 
package MyMVR;
#ABSTRACT: Moose subclass of Math::Vector::Real
use 5.008;
use Moose;
use namespace::autoclean;
use MooseX::NonMoose;
use MooseX::Storage;
with Storage ('io' => 'StorableFile' );
extends 'Math::Vector::Real';


__PACKAGE__->meta->make_immutable;

now using MVR->new works, 
use MyMVR;

my $a = MyMVR->new(0,0,0);
my $b = MyMVR->new(1,1,1);

print $_ ."\n" foreach (@{$a - $b});

[download]
with Moose warnings (that make sense) about MyMVR's new: "The new() method for MyMVR expects a hash reference or a key/value list. You passed an odd number of arguments at MyMVR_test.pl". The V function is no longer accessible. Any help achieving either goal is greatly appreciated! D
