=head1 NAME
Text::Bidi::Array::Byte - Dual-life byte arrays
=head1 VERSION
version 2.12
=head1 SYNOPSIS
use Text::Bidi::Array::Byte;
my $a = new Text::Bidi::Array::Byte "abc";
say $a->[1]; # says 98
say $$a; # says abc
say "$a"; # also says abc
=head1 DESCRIPTION
This is an derived class of L<Text::Bidi::Array> designed to hold C<byte>
arrays. See L<Text::Bidi::Array> for details on usage of this class. Each
element of the array representation corresponds to an octet in the string
representation, at the same location.
