Well, that's a fair point.  My only counterpoint would be this bit of code:

>     $class->_process_options($name, \%options) unless $options{__hack_no_process_options}; # used from clone()... YECHKKK FIXME ICKY YUCK GROSS

which leads me to believe that, eventually, someone is going to change
*something* about it. :-D

Well, both ealleniii and Todd provided alternatives which don't rely
on any private methods, but yours has the advantage of being the
absolute simplest (and least scary, really, private-method-meddling
and all).  So I think I'm going to go with this approach for now.  If
any other Moosites want to chiime in and tell me it's a terrible
thing, I'll consider that if I do end up getting that wild hair and
trying to wrestle it into a CPAN release.  But for now this works
really well and doesn't hurt my brain too much. :-)
