MooX::PDL2

This class provides the thinnest possible layer required to create a Moo
object which is recognized by PDL.

PDL will treat a non-PDL blessed hash as a PDL object if it has a hash
element with a key of "PDL". That element may be a "PDL" piddle or a
*subroutine* which returns a piddle.

This class provides a "PDL" method (which must not be overridden!) which
returns the contents of the "_PDL" attribute. That attribute is yours to
manipulate.

  Classes without required constructor parameters

PDL does not pass any parameters to a class' initialize method when
constructing a new object. Because of this, the default implementation
of MooX::PDL2::initialize() returns a bare piddle, not an instance of
MooX::PDL2, as it cannot know whether your class requires parameters
during construction.

If your class does *not* require parameters be passed to the
constructor, it is safe to overload the "initialize" method to return a
fully fledged instance of your class:

 sub initialize { shift->new() }

  Overloaded operators

PDL overloads a number of the standard Perl operators. For the most part
it does this using subroutines rather than methods, which makes it
difficult to manipulate them. Consider using overload::reify to wrap the
overloads in methods, e.g.:

  package MyPDL;
  use Moo;
  extends 'MooX::PDL2';
  use overload::reify;
