Summary: Blessed arrayrefs with Moose

Description:
Objects implemented with arrayrefs rather than hashrefs are often faster
than those implemented with hashrefs. Moose's default object implementation
is hashref based. Can we go faster?

Simply 'use MooseX::ArrayRef' instead of 'use Moose', but note the
limitations in the section below.

The current implementation is mostly a proof of concept, but it does mostly
seem to work.
