Damian's NEXT doesn't actually do the right thing either.  I had an
extensive email conversation with Damian and Paul Fenwick about this
last fall (Nov 2002).  I can forward this to you.  I haven't checked
whether it works right in Perl 5.8.

I have a somewhat kludgy solution that does work.  It's in
Bio::Root::AutoClass checked into CVS under branch-1-2-collection
(freaky-dev).  Note that the POD is in a separate file in the same
directory.  It does more than you're asking for -- also autogenerates
simple accessor methods, and does argument processing a little
differently than Bio::Root::Root.  I'd be happy to extract the
constructor invocation code and package that up separately if it does
what you want.  Of course, you're welcome to do this yourself if you
prefer.

Best, 
Nat
