What, Rose::DB::Object doesn't do lazy-loading? :) I think that's the 
sort of select that Bill was talking about.

We had a discussion about using callbacks vs. getting the data up front 
on the TT list a while ago.  The thread is here if anyone is interested:

I'm not entirely decided about this.  In theory I think it's probably 
better to get the data up front, but passing Class::DBI objects to a TT 
template is so easy that it's just about irresistible.
