Diab,
from my - very limited - experience with inheriting PDL
(PDL::IO::Nifti), I end using the native piddle ($myvar->{PDL}) for
everything than the most basic operations; I've wrapped that into a
method. Is this an acceptable work around for your use case? The
left-hand side will always have to accept a plain piddle, but it is
predictable.

Now, what about using Moose accessor methods to default to $myval->{PDL}?
