Kaj -
Your original email immediately brought to mind some experiments by Joel
(jberger) trying to directly subclass PDL using Moo, but I couldn't find
the email. I managed to dig it up, it was to the pdl-porters:
http://mailman.jach.hawaii.edu/pipermail/pdl-porters/2013-June/005695.html.
Upshot is this:
#!/usr/bin/env perl
use strict;
use warnings;
use v5.10;
{
package MyPDL;
use Moo;
use PDL::Lite;
extends 'PDL';
}
my $x = MyPDL->xvals(10,10);
my $y = MyPDL->yvals(10,10);
say ref $x;
print $x - $y;
That said, if you simply want to create a Moo[se] class that has a PDL
attribute, you should simply be able to "use PDL::Lite" and then declare
said attribute isa => 'PDL', and you should be all set.

"Debugging is twice as hard as writing the code in the first place.
Therefore, if you write the code as cleverly as possible, you are,
by definition, not smart enough to debug it." -- Brian Kernighan
