[perl #29230] Class::Struct, accessor overrides not called from constructor

Class::Struct allows you to override the accessors it creates, but it
doesn't call them in its constructor.
In other words,

     $struct->field('blah');

calls my override, but

     $struct = structure->new('field' => 'blah');

doesn't. Class::Struct simply does

     $r->{'field'} = $init{'field'}

but it would be more useful if it did

     $r->field($init{'field'})
