perldoc Moose::Manual::Delegation calls it "Attribute delegation", but
actually you're not delegating attributes. Instead, you are delegating
method calls to an attribute of your class.

So this is what you are missing: Calling Class->new simply isn't calling
$object->thing underneath.  If you add MooseX::StrictConstructor to your
package Class, it will barf at you saying

   Found unknown attribute(s) init_arg passed to the constructor: thing

BUILD or BUILDARGS can help to achieve what you're trying to do.
